given a four-value enum "enum1" (its values indexed [0,3]) that is a discriminator for a union "union1", allowable values for

union1Helper.type().member_label(int)

should be 0 through 3 inclusive, or the function throws a Bounds exception. The returned enum1-carrying Any object's data should correspond to the index provided by the call. Instead, the value returned by a given index of 0 gives the value for 1, and when a value of 3 is specified the function throws a Bounds exception. As expected, a value of -1 correctly throws a Bounds exception.
