It seems to me we've seen this three times in six weeks.  comp.lang.c has a
Frequently Asked Qestions list that is posted periodically.  Is it time for
comp.lang.c++ to get a FAQ of its own?

If I could promise the time to do it, I'd volunteer.  For the present, I can't.
But if anyone would like to, here's one reader who would be grateful.

Oh, the correct answer to the question is  ReadTheFructatingManual!  The useful
answer is `Omit the argument name in the argument list, but leave the type (as
though you were casting).'
