Dave, can we possibly prefix this with V8, so that it's clear that this is a V8-specific modification. Also, I want to make sure Sam is ok with this. Adding him to cc.
I had it that way at one point, but Mike felt that it was better to do it without #ifdef'ing it
Seems fine to me. The CustomSetter clearly overrides this for JSC.
Gah. I didn't realize I wasn't on cc list.
Assigned to levin for landing.
