mypyc crashes with ParamSpec #15409
Description
I did my first try with mypyc but it directly crashes when I use ParamSpec
To Reproduce
from __future__ import annotations
from typing import Any, Callable, TypeVar, ParamSpec
PARAM = ParamSpec("PARAM")
RET = TypeVar("RET")
def decorator() -> Callable[[Callable[PARAM, RET]], Callable[PARAM, RET]]:
def _wrapper(function: Callable[PARAM, RET]) -> Callable[PARAM, RET]:
def _inner(*args: PARAM.args, **kwargs: PARAM.kwargs) -> Any:
return function(*args, **kwargs)
return _inner
return _wrapperExpected Behavior
Works
Actual Behavior

The original example works on master, likely fixed by #15837
