I highly recommend reading perlvar about all those regex match variables, it's full of "hidden" gems. 
#!/usr/bin/perl
use strict;
use warnings;
use 5.010;

my $string = "CATINTHEHATWITHABAT";
my $regex = qr{\wAT}i;
my @matches = ();

while ($string =~ /($regex)/pg){
    my $start = $-[0];
    my $end = $+[0];
    my $hitpos = "$start-$end";
    say "${^MATCH} found at $hitpos";
}
