Looks as Python version of functools.partial() needs a fix. Reimplementations of the pure-Python itemgetter and attrgetter to automatically pickleable Python classes have a disadvantage. It makes the pickling incompatible between Python and C versions. This means that itemgetter pickled in CPython will be not unpickleable on Python implementation which don't use C accelerator and vice versa. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22955> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
