Ned, I'm happy to do this. While the ability to join wasn't documented, it's not an unreasonable expectation. I'm not sure it's possible to fail _unless_ the regexps use named groups (and/or numbered backreferences) - and nobody in their right mind would expect regexps for such simple patterns to do such a thing ;-) So chances seem decent the regression your user stumbled into wouldn't be the only one to pop up. The fix was actually quite easy (and thanks to Anthony for nudging me in that direction!). The annoying part was writing a test given that the precise group names generated are no longer predictable :-( ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40480> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
