Mike's recommendation is the same API introduced by jQuery a few years ago
and since then, there have been many requests to expand the signature to
other jQuery APIs. The toggle('bar baz') is not a good example, it should
be illustrated with .add() and .remove():

foo.add("many class name strings");
foo.remove("many class name strings");


Adding >1 class at a time is a _very_ common pattern in "real world" web
development.
