-    If a generic type is commonly generic over just one type you can use

-        T = TypeVar("T", default=int)

-    A TypeVar without a default cannot follow a TypeVar with a default.

     At runtime, ``isinstance(x, T)`` will raise :exc:`TypeError`.  In general,
     :func:`isinstance` and :func:`issubclass` should not be used with types.
