AFAICT, this change was the most controversial part of PEP 380.

PS I'm attaching a patch to the letter; it's far from ideal state, but contains the GeneratorReturn exception, code to raise it and the corresponding unittests.

I believe overloading StopIteration for this purpose was considered more acceptable than creating a new exception. BTW, attaching patches to emails on this list is generally the best way to have few look at your patch. :-p Also, this seems more appropriate for python-ideas.
