[Python-ideas] Complete typing.Union with the rest of set-like functions

[Ivan Levkivskyi]

Intersection has already been proposed, see
https://github.com/python/typing/issues/213
But it is not yet implemented. You can show your use cases on the typing
issue tracker,
maybe they can be covered by Intersection (which will be most probably
added at some point).
