Dmitry, Please present to comp.lang.ada a minimal* itemized list of A) the extant portions of the Ada2012 typing-system whose presence obstruct= s what you are seeking along with why these presences obstruct your vision B) the lacks within the Ada2012 typing-system whose absence obstructs what = you are seeking along with why these absences obstruct your vision. * minimal =3D not everything plus the kitchen-sink that world+dog thinks is= trendy & cool. Rather, please focus on only those few portions that could= be applied to great advantage in Ada without wholesale replacement of Ada'= s entire typing-system (or worse, Ada's entire runtime semantic system) wit= h, say, OCaml's entire typing-system, warts & all.
