        e.g.::

          somecolumn.op("*")(5)

        produces::

          somecolumn * 5

        This function can also be used to make bitwise operators explicit. For
        example::

          somecolumn.op('&')(0xff)

        is a bitwise AND of the value in ``somecolumn``.

        :param operator: a string which will be output as the infix operator
          between this element and the expression passed to the
          generated function.

        :param precedence: precedence to apply to the operator, when
         parenthesizing expressions.  A lower number will cause the expression
         to be parenthesized when applied against another operator with
         higher precedence.  The default value of ``0`` is lower than all
         operators except for the comma (``,``) and ``AS`` operators.
         A value of 100 will be higher or equal to all operators, and -100
         will be lower than or equal to all operators.

        :param is_comparison: if True, the operator will be considered as a
         "comparison" operator, that is which evaluates to a boolean
         true/false value, like ``==``, ``>``, etc.  This flag should be set
         so that ORM relationships can establish that the operator is a
         comparison operator when used in a custom join condition.

         .. versionadded:: 0.9.2 - added the
            :paramref:`.Operators.op.is_comparison` flag.

        :param return_type: a :class:`.TypeEngine` class or object that will
          force the return type of an expression produced by this operator
          to be of that type.   By default, operators that specify
          :paramref:`.Operators.op.is_comparison` will resolve to
          :class:`.Boolean`, and those that do not will be of the same
          type as the left-hand operand.

          .. versionadded:: 1.2.0b3 - added the
             :paramref:`.Operators.op.return_type` argument.

        This is the lowest level of operation, raises
        :class:`NotImplementedError` by default.

        Overriding this on a subclass can allow common
        behavior to be applied to all operations.
        For example, overriding :class:`.ColumnOperators`
        to apply ``func.lower()`` to the left and right
        side::

            class MyComparator(ColumnOperators):
                def operate(self, op, other):
                    return op(func.lower(self), func.lower(other))

        :param op:  Operator callable.
        :param \*other: the 'other' side of the operation. Will
         be a single scalar for most operations.
        :param \**kwargs: modifiers.  These may be passed by special

    :class:`.custom_op` is normally instantiated when the
    :meth:`.Operators.op` or :meth:`.Operators.bool_op` methods
    are used to create a custom operator callable.  The class can also be
    used directly when programmatically constructing expressions.   E.g.
    to represent the "factorial" operation::

        from sqlalchemy.sql import UnaryExpression
        from sqlalchemy.sql import operators
        from sqlalchemy import Numeric

        unary = UnaryExpression(table.c.somecolumn,

    :class:`_expression.ColumnElement` expressions.

    By default, all methods call down to
    :meth:`.operate` or :meth:`.reverse_operate`,
    passing in the appropriate operator function from the
    Python builtin ``operator`` module or
    a SQLAlchemy-specific operator function from
    :mod:`sqlalchemy.expression.operators`.   For example
    the ``__eq__`` function::

        def __eq__(self, other):
            return self.operate(operators.eq, other)

    Where ``operators.eq`` is essentially::

        def eq(a, b):
            return a == b

    The core column expression unit :class:`_expression.ColumnElement`
    overrides :meth:`.Operators.operate` and others
    to return further :class:`_expression.ColumnElement` constructs,
    so that the ``==`` operation above is replaced by a clause
    construct.

        In a column context, produces the clause ``column IN <other>``.

        The given parameter ``other`` may be:

        * A list of literal values, e.g.::

            stmt.where(column.in_([1, 2, 3]))

          In this calling form, the list of items is converted to a set of
          bound parameters the same length as the list given::

            WHERE COL IN (?, ?, ?)

        * A list of tuples may be provided if the comparison is against a
          :func:`.tuple_` containing multiple expressions::

            from sqlalchemy import tuple_
            stmt.where(tuple_(col1, col2).in_([(1, 10), (2, 20), (3, 30)]))

        * An empty list, e.g.::

            stmt.where(column.in_([]))

          In this calling form, the expression renders a "false" expression,
          e.g.::

            WHERE 1 != 1

          This "false" expression has historically had different behaviors
          in older SQLAlchemy versions, see
          :paramref:`_sa.create_engine.empty_in_strategy`
          for behavioral options.

          .. versionchanged:: 1.2 simplified the behavior of "empty in"
             expressions

        * A bound parameter, e.g. :func:`.bindparam`, may be used if it
          includes the :paramref:`.bindparam.expanding` flag::

            stmt.where(column.in_(bindparam('value', expanding=True)))

          In this calling form, the expression renders a special non-SQL
          placeholder expression that looks like::

            WHERE COL IN ([EXPANDING_value])

          This placeholder expression is intercepted at statement execution
          time to be converted into the variable number of bound parameter
          form illustrated earlier.   If the statement were executed as::

            connection.execute(stmt, {"value": [1, 2, 3]})

          The database would be passed a bound parameter for each value::

            WHERE COL IN (?, ?, ?)

          .. versionadded:: 1.2 added "expanding" bound parameters

          If an empty list is passed, a special "empty list" expression,
          which is specific to the database in use, is rendered.  On
          SQLite this would be::

            WHERE COL IN (SELECT 1 FROM (SELECT 1) WHERE 1!=1)

          .. versionadded:: 1.3 "expanding" bound parameters now support
             empty lists

        * a :func:`_expression.select` construct,
          which is usually a correlated
          scalar select::

            stmt.where(
                column.in_(
                    select([othertable.c.y]).
                    where(table.c.x == othertable.c.x)
                )
            )

          In this calling form, :meth:`.ColumnOperators.in_` renders as given::

            WHERE COL IN (SELECT othertable.y
            FROM othertable WHERE othertable.x = table.x)

        :param other: a list of literals, a :func:`_expression.select`
         construct,
         or a :func:`.bindparam` construct that includes the

        produces an "empty not in" expression.   This defaults to the
        expression "1 = 1" to produce true in all cases.  The
        :paramref:`_sa.create_engine.empty_in_strategy` may be used to
        alter this behavior.

           :meth:`.ColumnOperators.notin_` operators

        Produces a LIKE expression that tests against a match for the start
        of a string value::

            column LIKE <other> || '%'

        E.g.::

            stmt = select([sometable]).\
                where(sometable.c.column.startswith("foobar"))

        Since the operator uses ``LIKE``, wildcard characters
        ``"%"`` and ``"_"`` that are present inside the <other> expression
        will behave like wildcards as well.   For literal string
        values, the :paramref:`.ColumnOperators.startswith.autoescape` flag
        may be set to ``True`` to apply escaping to occurrences of these
        characters within the string value so that they match as themselves
        and not as wildcard characters.  Alternatively, the
        :paramref:`.ColumnOperators.startswith.escape` parameter will establish
        a given character as an escape character which can be of use when
        the target expression is not a literal string.

        :param other: expression to be compared.   This is usually a plain
          string value, but can also be an arbitrary SQL expression.  LIKE
          wildcard characters ``%`` and ``_`` are not escaped by default unless
          the :paramref:`.ColumnOperators.startswith.autoescape` flag is
          set to True.

        :param autoescape: boolean; when True, establishes an escape character
          within the LIKE expression, then applies it to all occurrences of
          ``"%"``, ``"_"`` and the escape character itself within the
          comparison value, which is assumed to be a literal string and not a
          SQL expression.

          An expression such as::

            somecolumn.startswith("foo%bar", autoescape=True)

          Will render as::

            somecolumn LIKE :param || '%' ESCAPE '/'

          With the value of ``:param`` as ``"foo/%bar"``.

            :paramref:`.ColumnOperators.startswith.autoescape` parameter is
             now a simple boolean rather than a character; the escape
             character itself is also escaped, and defaults to a forwards
             slash, which itself can be customized using the
             :paramref:`.ColumnOperators.startswith.escape` parameter.

        :param escape: a character which when given will render with the
          ``ESCAPE`` keyword to establish that character as the escape
          character.  This character can then be placed preceding occurrences
          of ``%`` and ``_`` to allow them to act as themselves and not
          wildcard characters.

          An expression such as::

            somecolumn.startswith("foo/%bar", escape="^")

          Will render as::

            somecolumn LIKE :param || '%' ESCAPE '^'

          The parameter may also be combined with
          :paramref:`.ColumnOperators.startswith.autoescape`::

            somecolumn.startswith("foo%bar^bat", escape="^", autoescape=True)

        Produces a LIKE expression that tests against a match for the end

        Since the operator uses ``LIKE``, wildcard characters
        ``"%"`` and ``"_"`` that are present inside the <other> expression
        will behave like wildcards as well.   For literal string
        values, the :paramref:`.ColumnOperators.endswith.autoescape` flag
        may be set to ``True`` to apply escaping to occurrences of these
        characters within the string value so that they match as themselves
