Right, I think both are indeed enums at some conceptual level. IDL gives that concept a name; ES does not. It would be nice if IDL enums followed ES semantics, of doing `ToString(value)` (which may throw a `TypeError`) and then throwing a `RangeError` if outside the allowed range.
However, the [definition of `RangeError`][1] probably needs some updating in that case: > Indicates a numeric value has exceeded the allowable range.
