Just noodling around and -- Shazam! lightening struck (or maybe it was just that the dim bulb went on) --
but every time I have to process two arrays of differing lengths, in parallel, I have to go hunting for instructions or code-to-cargo-cult and maybe also for those remnants of hair I've just extracted trying to recall a decent approach.

So, does the algorithm implemented in the following code have an accepted name? or is it so dumb, it's known for the forcefulness with which it's been critiqued/criticized (and if so, why)? ...or (by some unlikely chance) novel?

#!/usr/bin/perl
use 5.016;
use warnings;

# Parallel processing of two arrays with different numbers of elements

my @arr=qw/a b c d e/; 
my @bar = qw/12 34 56/; 
my $i = 0;
while ($i<($#arr+2)) { 
    no warnings 'uninitialized';
    say "\t \$i: $i"; 
    say "\t\t $arr[$i], $bar[$i]";
    ++$i; 
}

Execution:

C:\>D:\_Perl_\PMonks\parallelArrayProcess.pl
         $i: 0
                 a, 12
         $i: 1
                 b, 34
         $i: 2
                 c, 56
         $i: 3
                 d,
         $i: 4
                 e,
         $i: 5
                 ,
