Another subject-area-specific option: Elixir. I do like every option you've presented as well; Elixir just fills another niche.

I was considering mentioning erlang, but you probably don't want to write erlang. I've never touched elixir, but I would likely try it if I hit a problem that I would use erlang for in the olde days.
