The fact that, in the context of *unique* symbols, the unforgability
property of the symbol is pointless indicates to me that we might have a
mixing of orthogonal concerns.
That leaves default non-enumerability. Consider the fact that object
literal methods are enumerable. Why should choosing a "unique name" as
opposed to an identifier for a method have any bearing on enumerability?
