I wish the nu-shell stuff was set up so that its language could be used as a Rust crate independentl of the shell? Like in your own runtime? Because it's not a bad general scripting language and kind of makes sense to me to embed in things like editors etc. Places where people would use Tcl (e.g. hw eng / fpga tools etc) or a Lisp (emacs) or an embedded Python/Lua now.

But when I looked at their crate structure it did not seem like this was possible. I don't love nushell the language but it actually fits a niche that not much else fits.
