I have a function, and I'd like to do several checks on arguments
before evaluating it. If some check fails, I want the function to
return unevaluated and print corresponding error message, what's the
proper style of doing it?
Help for "Message" gives an example for a single check, but it seems
awkward to use same form for multiple checks.
