heh, recompiling the regex was wasting 80% of my time :D
Every so often I look for a library that will compile the regex at compile time - iirc, there’s some stuff needing to made const fn before that can happen.
Last time I used regex, lazy_static was the way to go; I assume that regex can go in OnceCell nowadays.
I just passed it around, felt easier and rust-like. Compile time would be nice, but I have a vague feeling this would be too restrictive for some regexes/engines?
Maybe? There’s some deep wizardry shown in some people’s macros so a regex feels fairly basic in comparison.
