But here the parens make the tuple too:

  >>> foo = tuple
  >>> print(type(foo))
  <class 'type'>
  >>> len(foo)
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  TypeError: object of type 'type' has no len()

(totally just yanking chains, throwing pebbles in the pond to watch
the ripples, and otherwise sewing confusion ;-)
