Do you mean setting sys.argv as a solution sucks? No, I don't, I think it
is grand. If sys.argv was unmodifiable, *that* would suck.
Or do you mean that trying it as a solution to the problem of answering
the OP's question sucks? Well, no, experimentation is good for answering
these sorts of questions, and I can't assume that the documentation will
cover every imaginable use-case, or that users will find it. In the
absence of any documentation stating otherwise, I would have assumed that
sys.argv was an ordinary list which you can modify at will, but having
been caught out on faulty assumptions before, I would try it and see
before commenting publicly.
