Ok, so I thought I knew perl pretty well. I sling it on a daily basis. This one has me stumped. Anybody know of a faster way to do this? 
# Change 'from' to 'to' throughout 2D-array
sub propogate {
    my($arry) = shift;
    my($from) = shift;
    my($to) = shift;
    my($row);

    map {
        map {
            $_ = $to if($_ == $from);
        } @{$_};
    } @{$arry};
};
