Curious what you use instead of bash? When you spin up a server somewhere, what's the first thing you like to install that replaces what we typically use bash for?
Do these apply to NuShell? I think something like that is the way forward. Something with real data types rather than implicitly doing weird array processing. I would be pretty happy with something similar to Python but with easier IO redirection and subprocess management. xonsh is neat in principle, but painful in actual usage ime. And I suspect vulnerable to similar issues around the Python-bash interop.
I'd be happy with AngelScript or smth. Hard-typed, but interpretable. But not Python[-like]. I'd kill it with SIGFIRE.
