The intent of 51b635e81958 was avoiding needless copying. But this caused to leaking tuple subtype in case of single var-positional argument without other positional arguments. The intent of tests was checking that tuple subtype is not leaked to called function. There is a bug, but I need to find the place where tuple subtype should be converted to tuple without needless hitting performance. ---------- assignee: -> serhiy.storchaka components: +Interpreter Core stage: commit review -> needs patch versions: +Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28086> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
