I wouldn't go for:
getElementsByClassName("foo", "bar")

Because that's not ideal in my opinion, since that makes harder to add an  
arbitrary number of classes to search for programatically.

I would go for:
getElementsByClassName("foo bar")

But, as you said, that can add some confusion. Therefore, this is ideal:
getElementsByClassName(["foo", "bar"])
