To answer my own question, I think Rust might be it (for manual memory management/"secure"):
http://blog.rust-lang.org/2015/04/03/Rust-1.0-beta.html "The final Rust 1.0 release is scheduled for May 15th" - today. There probably will not be any official "complementary language". I'm aware of PyCall and: Stefan Karpinski - Julia + Python = ♥ https://www.youtube.com/watch?v=PsjANO10KgM [I can assume Python would be very close to "official", for library/"battery included"-reasons, for the short (or long) term, but not for any inherent advantage as a (core) language.] http://quant-econ.net/python_or_julia.html [I haven't finished Karpinski's video..], he talks about pure (Haskell) vs. unpure. I do not think he talks about GC vs. manual memory management. For a short list of languages, does Rust (or C/C++) need to be on it? Or nim: http://nim-lang.org/ "Pointers to garbage collected memory are distinguished from pointers to manually managed memory." I'm skeptical that most people actually need a language with manual memory management (Strostrup isn't..). I think C (and maybe C++?) should be left out in favour of Rust as it is safer. Other dimensions: Do you need pure? Then Haskell? Erlang? (is it in some ways better than Julia for concurrency?) Autoparallel: Chapel (do we need it? Going with autoparallel as default seems to be a mistake - confusing for users?) Does Chapel or X10 or other PGAS model language have a change of beating Julia or getting more popular? Logical: Prolog? Datalog? Minikaren? Most promising logical? Any other? Z, VHDL etc. .. -- Palli.
