Doesn't the new ruby JIT already do the same thing?

[agrafix]

It's certainly related -- not sure what kinds if specialisation the new ruby JIT does.

[d3nj4l]

I haven't looked into the new ruby JIT too deeply, but as far as I remember it had several limitations that made it slow Rails apps down instead. This would make it easier to select and optimise for specific methods instead.

Current Ruby JIT doesn't take any type hint.

[sosodev]

Yeah, this is pretty much how the JIT works.
