 * Tuple, used by listing the element types, for example
  ``Tuple[int, int, str]``.
+  The empty tuple can be typed as ``Tuple[()]``.
  Arbitrary-length homogeneous tuples can be expressed
  using one type and ellipsis, for example ``Tuple[int, ...]``.
  (The ``...`` here are part of the syntax, a literal ellipsis.)
