Re: performing a function on corresonding array elements

Algorithm::Loops also handles parallel looping wonderfully:

use Algorithm::Loops qw( MapCarU );
use List::Util qw( sum );

my @items = map { $_->{items} } @sets;
my @totals = MapCarU { sum( @_ ) } @items;

And, of course, it also works without the temporary array variable: `... my @totals= MapCarU { sum( @_ ) } map $_->{items}, @sets;` [download] - tye	[reply] [d/l]

Which is exactly how I'd write it for myself. I thought I'd opt to be clearer. ⠤⠤ ⠙⠊⠕⠞⠁⠇⠑⠧⠊	[reply]
