Having
# foo.py
from autocommand import autocommand
@autocommand(__name__)
def main(arg: int):
passthe python -m foo m command correctly reports an error:
usage: foo.py [-h] arg
foo.py: error: argument arg: invalid int value: 'm'However, adding from __future__ import annotations on top of the module breaks this and skips validation:
Having
# foo-ann.py
from __future__ import annotations
from autocommand import autocommand
@autocommand(__name__)
def main(arg: int):
passthe python -m foo-ann m command works just fine.

Current string-check argument parsing is pretty naive and doesn't work for postponed annotations. https://peps.python.org/pep-0563/
