New submission from flying sheep: _TypeAlias claims in its docstring that “It can be used in instance and subclass checks”, yet promptly contradicts itself if you try it: “Type aliases cannot be used with isinstance().”
it would be useful to either document (and therefore bless) type_impl, or make it actually work with isinstance (probably by delegating to type_impl) ---------- components: Library (Lib) messages: 256154 nosy: flying sheep priority: normal severity: normal status: open title: _TypeAlias: Discrepancy between docstring and behavior type: behavior versions: Python 3.5, Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25830> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
