Eric V. Smith <eric at trueblade.com> added the comment:
No. parse_known_args assumes you have known and unknown args intermixed.
Going back to the original example, what if "hack" and ":target" had overlapping parameter names (say, they both supported "--arg1")? I think parse_known_args would pick up all instances of "--arg1". I really want "--" to mean "treat everything else as non-optional arguments".
Whether that's the original intent, I don't know. But as David says, unless it is, it's impossible to implement such a scheme with argparse.
