[Python-ideas] How can I get own instance of generator in itself code

[David Townshend]

The problem with PEP 3130 was the PEP itself, not the idea.  I believe Eric
Snow was working on a patch to implement this (see
http://code.activestate.com/lists/python-ideas/11234/ and
http://bugs.python.org/issue12857), but I'm not sure what its current
status is.
