@timbray I wonder how close the match is to #Hyperscan. That’s Intel’s high-perf regex engine, which disallows backreferences, lookarounds and capture groups, much like I-Regex.

If you want more fodder for considering which regexes would work in your spec, they have a corpus of thousands available.

Hyperscan does allow `.`, `\s`, `\d` and so on, so you’re even stricter!
