Finally non cringe entry points!

entry_point.py

# utils.py
from sys import argv
from typing import Any, Callable

def entry_point(
	func: Callable[[list[str]], Any] | Callable[[], Any]
) -> Callable[[], Any]:
	new_func = lambda: func(argv) if func.__code__.co_argcount == 1 else func()  # type: ignore
	if func.__module__ == "__main__":
		new_func()
	return new_func



# runner.py
from utils import entry_point

@entry_point
def main(argv: list[str]):
	print(argv)


@entry_point
def main2():
	print("nice")
	
# `if __name__ == "__main__": ...`? ew... ugly
