There are differences between typing.Union and types.Union:

* typing.Union is indexable, types.Union is not.
* types.Union is a class, typing.Union is not.

types.Union corresponds to typing._UnionGenericAlias, not typing.Union. It is confusing that typing.Union and types.Union have the same name. Note also that most classes in the types module have the "Type" suffix: FunctionType, MethodType, ModuleType, etc. I think that it would be better to rename types.Union to types.UnionType.
