Patch Expected File

I’m probably not qualified to review the patch. But was just wondering: Would it be faster to do an early exit if the two values are identical before doing any type checking? Then if the type is object we can return false. It seems that this makes strict equality comparisons of objects that turn out to be equal faster without slowing down the ones that turn out to be not equal. But maybe it would slow down some other important cases? Besides objects, I believe that undefined, null, booleans, and integers would all benefit from this. Floating point numbers and strings might be slowed down slightly by the extra check, I guess.
