[ruby-core:118245] [Ruby master Misc#20519] Porting regexp to pure ruby?

Issue #20519 has been updated by brightbits (Michael Baldry).


 I was at the kaigi but unfortunately missed that talk! I didn't realise a few weeks later I'd be digging in to it :) Looks like some interesting work has gone in to this area already. I'm going to spend some time looking in to this.

Thanks for the detailed response, I really appreciate it!

----------------------------------------
Would there be any benefit in porting Regexp from Onigmo to a pure ruby implementation that could benefit from YJIT? 

Compiling a pattern could be translating to a ruby method which would be optimized by YJIT easily. 

Has this been explored or any work done around this kind of thing, before I take a look in to it more? 

Many thanks
