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)
