""""""
Returns a tuple of all alternate types allowed by the `typ` type annotation.
If typ is a TypeVar,
* if the typevar is bound, return get_alternate_types_resolving_forwardref_union_and_typevar(bound)
* if the typevar has constraints, return a tuple containing all the types listed in the constraints (with
appropriate recursive call to get_alternate_types_resolving_forwardref_union_and_typevar for each of them)
* otherwise return (object, )
If typ is a Union, return a tuple containing all the types listed in the union (with
appropriate recursive call to get_alternate_types_resolving_forwardref_union_and_typevar for each of them)
If typ is a forward reference, it is evaluated and this method is applied to the results.
Otherwise (typ, ) is returned
Note that this function automatically prevent infinite recursion through forward references such as in
`A = Union[str, 'A']`, by keeping a _memo of already met symbols.
