It does!

I understand the motivation for not allowing "initialization-by-copy-constructor" by default, but I think this pattern may become more common. Enum values in WebIDL are turn into Strings in the bindings, and I've often defined "static const String& enumValue();" methods in tho bound classes to represent each enumerated value. A getter that can either return an enum value or throw an exception will likely hit this quirk.  It may be worth it to make an exception (hah!) for ExceptionOr<String> or ExceptionOr<AtomicString>.
