Copilot was super helpful for changing some locals to lazy_static!: let integer_re = Regex::new(...) // old static ref INTEGER_RE = Regex::new(...) // new Unfortunately, it added a $ to the end of my first regex! It saved me a ton of keystrokes, but needed careful checking.

I've started playing again with A* search instead of Dijkstra for difftastic. So far it's only saved me visiting 3% of graph nodes, which is negligible. A* works best when you have a good heuristic, but finding a good heuristic is hard. Currently:

Most of the code I write is in a garbage collected language. I'm often surprised how much extra performance I can get when I can control allocations. I saved ~10% runtime in difftastic by moving to a zero-allocation colour library (owo_colours)!
