My vote is for Elixir as well, but it's not a competitor for multiple important reasons. There are some languages in that niche, although too small and immature, like Crystal, Nim. Still waiting for something better.

P.S. Swift, anyone?

Last I checked Crystal’s compile time was too slow for me to deal with for anything beyond toy projects.

Swift on Linux has been a fairly horrible experience, but the language looks promising.
