I'd say you violated it right there ... (should have been)::
args = input.split()
cmd = arg.pop()
cmd = ''
FWIW, I've been +1 on * unpacking since I first saw the proposal, and
have yet to see a convincing argument against it other than people
wanting to stick the * anywhere but at the end. Perhaps I'll take the
stdlib challenge (unfortunately, I have to travel this weekend, but I'll
see if I can make time).
