Callable is very special generic. It differs in many ways from List or Awaitable. You cannot just use GenericAlias. Also, in contrary to list() or dict(), callable() is not a constructor, it is a predicate. callable[[int], str]() does not make sense. ---------- nosy: +serhiy.storchaka _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42102> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
