I don't think it is too late.  90% ++ of the python code base out
there doesn't use iterators yet... people are still wrapping their
minds around it to see how they can use it in their applications.
If it was publicly stated that this could be "fixed" in the next
version I don't think that it would hurt.  These things happen,
and sometimes its best to "roll back".  Programmers understand this.

Best,

Clark
