Interesting, wasn't aware of that. Then let's wait what will happen when users start manually adding signature information to the docstrings of their C code extensions and come asking for annotation support in order to allow for introspection of the expected parameter types. > You imply that __text_signature__ is improper and unsafe. What I'm saying is that the existing function introspection API would have provided a much better way to do these things, and that it's good to finally have the meta data available in the source code so that that API can be made available at some point. Sorry if my wording sounded offensive. > If in the future we need to change how we represent signatures, we can > remove it.

The feature is just way too visible. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17159> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
