this is a minimal working example of how to skip iterations within a list of numbers:

#!/usr/bin/env perl

use strict;
use feature 'say';
use warnings FATAL => 'all';
use autodie ':default';

foreach my $n (0..29) {
    if ($n % 4 == 0) {
        $n += 5; # goes to $n+1, even though I increased $n to $n+5
        next;
    }
    say $n;
}

I cannot alter $n so that it jumps several iterations within the number.

That is, I want next to move 5 up, not 1.

How can I skip multiple iterations of a foreach loop?
