It would be great to have a language that is a love child of Erlang and Rust. All I need is: repl, message passing, actor model, lightweight-threads and strong types. :)
It really is the best of both languages... unfortunately, the main supporter of Pony seems to have stopped using it in favour of Rust though :D.
But if that's really what you want, Pony is your language. It definitely deserves more love.
