I had vague plans to bug Graham (yay, spelling!) about proposing wrapt for inclusion in 3.5 (possibly split between functools and types rather than as a completely new module, though). functools.wraps was always intended as a near term workaround that, like most sufficiently effective workarounds, ended lasting years before its limitations irritated anyone enough for them to go back and do it right :) Cheers, Nick. > > > -- > Steven > _______________________________________________ > Python-Dev mailing list > Python-Dev at python.org > https://mail.python.org/mailman/listinfo/python-dev > Unsubscribe: https://mail.python.org/mailman/options/python-dev/ncoghlan%40gmail.com -------------- next part -------------- An HTML attachment was scrubbed...
