This sets ``__args__`` to a tuple containing the flattened``argtypes``

Example: ``Callable[[int, str], float]`` sets ``__args__`` to
``(int, str, float)``.

a+ Compute the hash value of a set.
Note that we don't define __hash__: not all sets are hashable.
But if you define a hashable set type, its __hash__ should
call this function.
This must be compatible __eq__.
All sets ought to compare equal if they contain the same
elements, regardless of how they are implemented, and
regardless of the order of the elements; so there's not much
freedom for __eq__ or __hash__. We match the algorithm used
by the built-in frozenset type.
