No, no, no. Start over.
1. There is a need.
2. It doesn't matter what order the user gives the options in, the
result should be the same.
You said you "*expect* '--foo --no-foo' to make foo be zero". I said
'why would you say "--foo --no-foo" if what you really meant was
"--no-foo"' (implying that the user had some sort of reason to say both
and that the order should not be interpreted in the literal and
aggravating way that seems to be the calling card of computers.)
Did you read the essay about why order doesn't matter?
