No, Dmitry, those are not "more important"; they are merely features that a= ccomplish some greater mission. I speak of the greater missions. For exam= ple, the already-existing portions of your #4 are features that permit prog= ramming in the large, which is needed by my #1, the military-aerospace indu= stry. Your #5 has always (since Ada1983 and Green) been viewed as essentia= l to my #1. The new innovations in your #4 would largely catch Ada202X up = to the (perceived-)innovations in C++2011 regarding concurrency; see N2239,= N2427, N2748, N2752, N2429, N2664, N2179, N2547, N2659, and N2660 at http:= //clang.llvm.org/cxx_status.html; the new innovations in your #4 would be b= e my #3.
