It's radically different, but the language where I've had the most pleasant repl-driven experience is Elixir. Because of how it's error handling works it's even sane to debug with a repl into live production in some cases.
I've started learning Elixir over the week and I can't see myself using Python for scripting again. They're very different languages but th experience feels similar, except I vastly prefer Elixir
I wouldn't expect elixir to be good at scripting. What sort of libraries do you use?
