I'd personally like this:
getElementsByClassNames(["array", "of","class","names"], bool any)
if any = true then get all elements that have any of the class names
provided, otherwise get all elements that have *all* class names provided.

True, but Ric has made an interesting point about the order of class
names, which does actually matter.
Do we want getElementsByClassNames() to work as "the final page render" or
just "logically"? I don't even know how to say it, but here's the idea:
You have the foo bar example provided by Ric, in which Fred and Wilma
paragraphs are blue, and Barney is red.
Do you want to be able to make the distinction between Fred, Wilma and
Barney with getElementsByClassNames(["foo", "bar"]) ? If the order doesn't
matter ... you can't.
This is getting way beyond control.
