My day 11 solutions seem to be awfully slow

[thundergnat]

I am mildly disappointed with the execution speed of my Raku day 11 solutions. They work, and return the correct answer (eventually) but they seem awfully pokey.

On my system: (7 year old processor) i7-4770 3.9 Ghz, 16Gb memory, Linux Mint 20, Raku v2020.11

Part 1 finishes in about 15 seconds and part 2 in about 30.

I haven't tried anyone else's solutions. I try to avoid spoiling if possible, but what have others experiences been? Is this task just time consuming? or am I just being really inefficient?

Just curious.

Update: Went through and used native vars wherever possible and that helped a bunch with part 2. Not so much with part 1. With latest commit, 1 is still just around 15 seconds, maybe a little less; 2 is now down around 19 seconds.
