In that case, it's already present, if a little more verbose, and there's
no huge cause for complaint.  I didn't think they could be used that way.

I probably tried an arithmetic function improperly in the past and assumed
it couldn't be done at all.  I'm used to the old "it either evaluates to
true or it doesn't, and anything non-zero is true" results from many other
languages.

But in this case, it's no huge deal.  It's fully functional.  Thanks for
the tip...that'll come in handy.
