Code Snippet

from typing import Callable, reveal_type


class A[**P, R]:
    @classmethod
    def from_fn(cls, fn: Callable[P, R]) -> "A[P, R]": ...


def f(a: int) -> str: ...


b = A[[int], str].from_fn(f)

reveal_type(b)  # Type of "b" is "A[(int), str]"

Expected behavior

The inlay hint should be shown like A[(int), str].
