@jntrnr For me, anything above a line or two is automatically in Python or (preferably) Rust, so a new scripting language isn't the biggest priority. On the command-line, I rarely do data processing, so that also doesn't doesn't give me much incentive.

What I'm really intrigued by is the idea of using nushell as an embedded scripting language, as a modern TCL. I imagine that'd be a lot of work though.
