Description

Are there any plans to add support for the following?

from django.core.management import BaseCommand

class Command(BaseCommand):
    def add_arguments(self, parser):
        group = parser.add_mutually_exclusive_group(required=True)
        group.add_argument('--foo', nargs='+', type=int)

    def handle(self, *args, **options):
        pass

When calling the above using call_command:

call_command('call_command_test', foo=[1, 2, 3])
# Raises: django.core.management.base.CommandError: Error: one of the arguments --foo is required

call_command('call_command_test', '--foo=1', '--foo=2', '--foo=3')
# Option 'foo' will be of value [3]

I can't think of any workarounds. Thank you!
