sub total {
   my $sum =0;

    map { $sum += $_ } @_;
    return $sum;

}

Let's fold a list. `use List::Util 'reduce'; sub total { return reduce { $a + $b } 0, @_; }` [download]	[reply] [d/l]

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.	[reply]

something about it not processing efficiently with mysql in some contexts eh? What does map have to do with mysql? O-o Peter L. Berghold -- Unix Professional Peter -at- Berghold -dot- Net; AOL IM redcowdawg Yahoo IM: blue_cowdawg	[reply]

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.	[reply]
