Day 24 was hard... This is an interesting and elegant approach. Thank you for sharing.

Skipped it due to time and ability constraints. Going for the cucumbers later...

Thank you! I quite liked that the solution was a small repurpose of a straight forward interpreter. The ALU->Rust compiler via partial evaluation coming in the next post also barely modifies the naïve interpreter.

I built that one after AoC concluded out of curiosity, but the contents of this post were my in the moment solution.

I had a not so great solution that took about 30 minutes to run, but since I was busy with Christmas things I'd run it, go about my things, stop by the computer later, fix a tiny mistake, and run it again. I kept thinking about cleaner ways to solve it, this was hard one.
