But that would be almost the reverse of the programmer's likely intent.
Whether it's (exit "bad arguments") on Windows or (exit 1) on Plan 9,
the intention of a random argument is almost certainly failure rather
than success, because as I said there is only one kind of success and
many kinds of failure. So if anything uninterpretable arguments should
be mapped to #f.
