Antoine> Flattening should only happen for instances of the exact type. I am attaching a variant of the patch that will only flatten if both nested and wrapping partial is of the exact type. Other possibilities would include flattening partial_subtype(f, ...) if type(f) == partial and if type(f) == partial_subtype, but I'll present only the least and most conservative variants. Antoine> When people create subclasses [of partial type], there's usually a reason for it. It is hard not to agree with this thesis, but I don't see how it follows that subclass writers will not benefit from flattening their instances. Can you suggest a use case where flattening in functools.partial subtype would be undesirable? ---------- Added file: http://bugs.python.org/file16091/no-nested-partial-exact.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7830> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
