They have. Both function and type classes have constructors and they are called when a function or class is created. Values of __name__, __qualname__ and __module__ attributes are directly or indirectly passed to constructors. We do not have generalized way to call arbitrary constructor with automatically passing __name__, __qualname__ and __module__. And it would be convenient. create namedtuple Point(x, y, z=0) create enum Mode(read, write, append) create NewType UserId(int) create TypeVar T _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/VIRQ44BQKO2ENNL42PCNCVHVLPZMTXYV/ Code of Conduct: http://python.org/psf/codeofconduct/
