This would force string conversion of arguments, which is what I want
to avoid, because some of those computations (user-defined ones) would
just be too costly.

It has to be if you want to avoid those computations and return a
meaningful value.  But the recursive argument-eating function is ok for
me, too.

Ok, I see.  This is certainly a way to do it, though it requires
the preprocessor.  It would still be nice to have an efficient, clean
solution without resorting to additional tools.  Thanks, anyway!
