It's not the most correct way to do it. |a + ""| performs ToPrimitive(a, hint = None), whereas ToString(a) performed ToPrimitive(a, hint = String). The former consults valueOf, then toString, the latter the reverse.
Argh, I had forgotten about the no-hint case there. It seems wrong still, but I forget the details from ES1 era.
Domenic's question of why you want an explicit ToString in the language remains. If there's a strong reason for it, Reflect.toString might be the answer.
