Raymond Hettinger <rhettin...@users.sourceforge.net> added the comment:
Returning the same object vs new object for bound methods is a non-guaranteed implementation detail (as long the other semantics remain true). I think Martin's real concern is that trying to intern bound methods would be a can of worms (one that I wouldn't want to open). FWIW, str.join ignored by this patch. The "str" builtin is an overridable builtin (LOAD_GLOBAL "str" LOAD_ATTR "join"). In contrast, ",".join or "{}".format does not have dynamically changeable behavior (LOAD_CONST "{}" LOAD_ATTR "format"). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6133> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
