Post #2864114

@pervognsen@mastodon.social @stoklund@oldbytes.space I used it once for submatches in a lexer generator, which obviously has a different set of constraints than a regex engine, e.g. you can ban ambiguity and you don't care about up-front cost. I haven't seen it used in a regex engine, but a lot of recent ones want to be DOS-resilient, so up-front determinization is out the window anyways.
