I agree this looks very dubious to me also. Classic KVC would only
raise an exception if the attribute were a scalar value. GSObjCSetVal
takes care of calling setNilValueForKey: (unableToSetNilForKey: with
GDL2) when the attempt is made to set NSNull (EONull) or nil to a scalar
value.
I haven't noticed this because GDL2 replaces the implementation of -base.
Cheers,
David
