New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>:
>>> import typing
>>> T = typing.TypeVar('T')
>>> P = typing.ParamSpec('P')
>>> C = typing.Callable[P, T]
>>> C[int, str, float]
typing.Callable[[int], str]
int substitutes P as [int], str substitutes T, and the third argument float is
ignored.
