    If the name 'symbol' is bound to a constant value by the Python code
    object 'code', return that value.  If 'symbol' is bound to an expression,
    return 'default'.  Otherwise, return 'None'.

    Return value is based on the first assignment to 'symbol'.  'symbol' must
    be a global, or at least a non-"fast" local in the code block.  That is,
    only 'STORE_NAME' and 'STORE_GLOBAL' opcodes are checked, and 'symbol'
    must be present in 'code.co_names'.
