To clarify from above; it's almost certainly not going to be web compatible to change how `void` works in expressions, so if another alternative isn't viable, then it's kind of a nonstarter.
A separate question is, how would `String` cover strings across realms, considering that `'abc' instanceof String` already returns `false` even in the same realm?
