Bug report

The following does not trigger an exception in ArgumentParser, where I would expect an exception since the default value for --choice is not in the list of choices:

import argparse

parser = argparse.ArgumentParser()
parser.add_argument('--choice', choices=['a', 'b', 'c'], default='foo')

args = parser.parse_args()                    # args.choice == 'foo'

This is at least inconsistent behaviour, the following piece of code does trigger an exception for an invalid default value:

import argparse

parser = argparse.ArgumentParser()
parser.add_argument('--num', type=int, default='foo')

args = parser.parse_args(args=[])

Environment: Python 3.10.9, Arch Linux, x86_64.
