Eric V. Smith <e...@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.
