I like Nim very much. It’s like Python to write in, very expressive and easy to read, but compiled. I think it’s a very good choice for small utilities as well as systems programming.

What I don’t like is some people in the project being dicks to others but I just use the language and try not to care about it.

I think Nim is the frontrunner here. Close to Python to write because it is so expressive, close to C speed because it is compiled properly.

There’s also URLCheck:
