C code can still quickly special case the generator type in the positive case, and it will usually be interested in an exact type match anyway. Determining that an object is *not* (compatible with) a generator might lead to some degradation, but in most cases, at least in the interpreter core, this would be an error case anyway, so being slower here should rarely hurt. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24018> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
