That isn't accurate, though.  In this case with_object isn't attached to 
an iterator--it's attached to an enumerator.  So I guess I should have 
simply said,

When with_object is called with a block, with_object returns its 
argument.

and avoided the issue of how ruby allows you to chain enumerators to 
both iterators and other enumerators.
