Chaining decorators

[lovetox]

Hi,

I seem to have problems with chanining decorators

from __future__ import annotations

from typing import Callable

import functools


def decorator(func: Callable[[int, str], None]) -> Callable[[int, str], None]:
    @functools.wraps(func)
    def func_wrapper(firstarg: int, secondarg: str) -> None:
        return func(firstarg, secondarg)
    return func_wrapper


class Test:
    def __init__(self):
        self.test(1, 'a')

    @staticmethod
    @decorator
    def test(firstarg: int, secondarg: str) -> None:
        print(firstarg, secondarg)


Test()

This code works, but pyright reports that test() has only one expected arg instead of 2.

It probably thinks it needs to strip away "self"? but as its a staticmethod this is not the case.

Or maybe i typed the decorator wrong

Yeah, pyright is treating it as though you had applied @decorator after the @staticmethod rather than the other way around. I'll create a bug report for this.
