  body: "   enum.reduce(initial, sym) => obj\n   enum.reduce(sym)          => obj\n   enum.reduce(initial) {| memo, obj | block }  => obj\n   enum.reduce          {| memo, obj | block }  => obj\n"
- !ruby/struct:SM::Flow::P 
  body: Combines all elements of <em>enum</em> by applying a binary operation, specified by a block or a symbol that names a method or operator.
- !ruby/struct:SM::Flow::P 
  body: If you specify a block, then for each element in <em>enum&lt;i&gt; the block is passed an accumulator value (&lt;i&gt;memo</em>) and the element. If you specify a symbol instead, then each element in the collection will be passed to the named method of <em>memo</em>. In either case, the result becomes the new value for <em>memo</em>. At the end of the iteration, the final value of <em>memo</em> is the return value fo the method.
- !ruby/struct:SM::Flow::P 
  body: If you do not explicitly specify an <em>initial</em> value for <em>memo</em>, then uses the first element of collection is used as the initial value of <em>memo</em>.
