Yes, I'm pretty sure because:

1. Compiled with jyjit confrmed (ruby --yjit) returns the correct value

2. RubyVM::YJIT.enabled? returned true

I didn't notice any improvements at basically so I can't really say _for sure_ if it was working as intended.

RubyVM::YJIT.enabled? returning true does seem to settle it, and no need to say "pretty sure" with qualifications!
