gollark: Rust has a COOL™ `regex` crate which can actually compile regexes to finite automatons of some kind, thus performance.

gollark: > In theoretical computer science and formal language theory, a regular language (also called a rational language[1][2]) is a formal language that can be expressed using a regular expressionhow helpful.
gollark: As in "regular languages"? It's a CS thing, I don't actually know what it means.
gollark: *Regular* expressions can't do that.
