T= his is a two-part request: 1) explicitly, the proposed feature/syntax and = 2) implicitly, the claim that no portion of Ada2012 can be utilized to acco= mplish that feature adequately with a different syntax (e.g., counter-claim= : another branch of this thread shows that generic enumerations sufficient= ly accomplish the OP's desired abstract enumerations, hence obviating the n= eed for a 2nd syntax to accomplish the desired effect).
