I understand, but both topics are closely tied together.  Cleanup code 
can be implemented in some __del__ method of some non-iterator object.  
This proposal doesn't address such cases, it focuses only on iterators.

My point is that it's not worth it to *significantly* change iteration 
(protocols and statements) in Python to only *partially* address the issue.
