Well, I didn't say I would like that. But the OP asked for the ad-hoc
creation of anonymous tuples, as in

   function Calculate(A, B, C: Integer; D, E, F: Float)
     return (Integer or Float);

(without actually suggesting a specific syntax; the syntax is mine), and 
my point was, that if you want tuples for Ada, you should ask to define 
them as proper types, rather than as ad-hoc anonymous types.
