[New-bugs-announce] [issue15847] parse_args stopped accepting tuples

[Zbyszek Jędrzejewski-Szmek]

New submission from Zbyszek Jędrzejewski-Szmek:

After recent change (78307 '#13922: argparse no longer incorrectly strips '--' after the first one.'), parse_args stopped working with a tuple
argument. It is easy to pass tuple to argparse by using positional function arguments:

def f(*args):
   parser.parse_args(args)

This will fail, because args is a tuple.

It is necessary to have at least one positional argument to trigger the bug.
