v2.6

Changes

• Added support for TypeVar types. It works like Union under the hood and both constraints and upper bound can be used to specify a variation of types. Similarly to Union it's recommended to place more complex variant types at first place like TypeVar("T", Dict[int, int], List[int]) not TypeVar("T", List[int], Dict[int, int]).
• Added support for short version of standard generic types without specifying type of objects kept in containers. Now it's possible to use List instead of List[Any] or Dict instead of Dict[Any, Any].
• Improved string representation of builtin and standard generic types. Now in the error messages you will see int instead of builtins.int or List instead of typing.List.
