The twenty years of waiting "paid off".
Yes. Indeed it has. Check out this Raku code of mine which is a solution for this years day 14. Any experienced programmer should be able to make sense of, and mostly understand it after spending 2 hours with the docs. I doubt the same is true for any perl implementation of similar brevity. 
my ( \o, \r ) =
    .head.comb.List,
    .tail.comb( /\w/ ).map( -> $a, $b, $c { "$a$b" => [ "$a$c", "$c$b"
+ ] } ).Hash
        with cache $*IN.slurp.split: "\n\n";

sub day14( \n )
{
    my %d = o.rotor( 2 => -1 )».join.Bag;
       %d = [(+)] %d.map({ r.{.key} »=>» .value }) for ^n;

    .Bag.values.minmax.elems - 1
        with ( o.tail => 1, |%d ).map: {
            .key.comb[0] => .value
        };
}

say day14 10|40;
