Not seeing much of a perf benefit from this, though Michal reports differently. More investigation is needed.
patch no longer applies. I wonder if I see bad behavior because I was testing with node or it was prior to the fixes around avoiding deoptimization.
I'll bring it up to date with the recent changes, thanks for the prod!
