Recently I stumbled upon https://crystal-lang.org/ and I love it!
It's really great fun to build stuff in Crystal, I don't have anything prod-grade yet to say how it scores there but the community seems to be happy about that too.
Crystal is slow to compile. There is a variant of Crystal that compiles a lot faster. But I forgot its name. Need to dig it up when I get back home.
I agree, the compiler is slow but I don't mind much, or better, the fact that I find building maintainable programs much easier outweights that downside massively in my case.
