Another potential yak shave. When we did the rename, we left an exception for STL-like things, so HashMap::find(), HashMap::end(), et cetera retained their lowercase names.

We should probably do the same for Get(): mixing casing of Get() in Blink seems rather confusing

(I'm marking this as an Oilpan bug, since the Oilpan handle classes are the most notable instance of this, though I'm sure there are others)

The flip side of this is that v8 mostly uses Get() as well (though they have a few get() thrown in there). But I think it's probably still worth standardizing on get() in Blink?
