Checking the source, I see the "magic" happens in pickle's `whichmodule` function when looping over `sys.modules` if `__module__` is not found. If that case, why check for `__module__` in the first place? wouldn't it be simpler to always loop over sys.modules? Is it to avoid looping over `sys.modules` whenever possible? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue28869> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
