[webkit-dev] For your consideration: Naming scheme for fooIfExists/ensureFoo

If the semantic is essentially that of a getter that just happens to lazily create what it gets on demand, then I don't think "require" or "required" is needed. It can just be named as a getter. If the side effect is very important and especially if clients ever call the function only for its side effect, then a verb phrase would be better. I am not sure which applies in this case.
