Re^2: Rook question

Let's fold a list.

use List::Util 'reduce';

sub total {
  return reduce { $a + $b } 0, @_;
}

The above code hardly even resembles Perl as I know it. Got a lot to learn... I've heard at work they use 'map' regularly (I wouldn't say 'frequently'--something about it not processing efficiently with mysql in some contexts). I'll need to read up on that.

something about it not processing efficiently with mysql in some contexts

eh? What does map have to do with mysql? O-o

I can't say I'd choose cowdawg's approach for this question, because map is a bit ill suited for this specific problem. Athanasius's is probably the most idiomatic while still being easy to understand.
