Adding a config file that allows you to do this should be easy enough. The tricky thing will be deciding on a good syntax for specifying how to invoke the...

How does a 1-pass NFA simulation compare with an NFA simulation that does lookahead before spawing new threads at branch points? It seems like the advantage of a 1-pass simulation...

> and it seems to me like an engine that does lookahead at every branch will never spawn more than 1 thread for a 1-pass NFA. I should have said...

Oh, now that you mention the PikeVM I realize that the lookahead version would have to do lots of extra work to copy capture group info around because it wouldn't...

So I've been quitely spinning my wheels on this for the last month or so, and after a few embarrassing false starts I think I've gotten [something](https://github.com/ethanpailes/regex/blob/one-pass-nfa-opt/src/onepass.rs) worth talking about...

I know this is a pretty big wad of code and issues to cough up, so if you are interested in triage: comments about the EmptyLook stuff and pontification on...
