[issue8609] itertools: problem with nested groupby, list()

You'd be better off asking this on the python mailing list http://mail.python.org/mailman/listinfo/python-list (or in some other forum);  this tracker is for reporting bugs in Python itself, not bugs in code written in Python.

[The problem you're encountering here is that you can only iterate over the return of itertools.groupby once.  That's by design, though:  it's not a Python bug.]
