I don't think this would be creating TMWTDI. Given the
proposed feature, and a suitable helper, then

   def Foo as NamedTuple('x', 'y', 'z')

would become the *obvious* way to define a named tuple
type. The old way

   foo = namedtuple(something, 'x', 'y', 'z')

would become something low-level that you only use in
special circumstances -- like calling type() directly
to create a class.
