Add convenience function that combines WTF::visit(...) with WTF::makeVisitor(...)
Created attachment 292133 [details] Patch
I went with WTF::switchOn(...) for this, but other names that were considered were: attend() walk() switchOver() route() choose() access() vary() match() pick() My top two favorites were switchOn(...) and match(...).
