List::Comprehensions is a Perl module that allows for list comprehensions in Perl.

SYNOPSIS

use List::Comprehensions;
use warnings;

my @res = ();

@res = comp1 { [ @_ ] } [0..4], [0..4], [0..4];

no warnings once;
@res = comp2 { [$i, $j, $k] }
i => [0..4],
j => [0..4],
k => [0..4];

# if strict vars is on, use lexicals. eg:
use strict vars;

my ($i, $j, $k);
@res = comp2 { [$i, $j, $k] }
i => [0..4],
j => [0..4],
k => [0..4];

# each being less efficient but equivelant to

@res = ();
for $i ( 0..4 ) {
for $j ( 0..4 ) {
for $k ( 0..4 ) {
push @res, [$i, $j, $k];
}
}
}
