Support Any(val)? #33

I just noticed that mypy's typing.py says that Any can be used to cast a value to type Any. E.g.

x = 42  # type: int
y = Any(x)
y.append(42)  # No error

Do we want/need this? What other notation could be used that we already support?

Mypy understands Any(x) as an alternative syntax for cast(Any, x). It's just a small convenience feature and not essential.

Let's not have that in the PEP.
