Agreed, this is the correct-and-most-concise way to do it. It should
throw on symbols, that's important.
Having String(sym) not throw is a win for other reasons Arv identified,
but using String(any) to invoke ToString is verbose and fragile, because
String could be rebound :-P. Use +'' if you want ToString in the
language, I say.

If `x` is an object, x + '' performs ToString(ToPrimitive(x, <no
hint>)), whereas String(x) performs ToString(ToPrimitive(x, hint
String)). So both expressions are not always interchangeable.
