I'm curious about this too. The latest 1.9 changes make it so that package precompilations are stored and reused, so the actual workflow will have to be to generate a package (which Julia has tools for), and have the script be just a tiny driver that calls into the package. With that workflow, what kind of latency can we expect? And how consistent would that be?

you can do it but it's not great. there's no batteries-included standard argparse library and even with the new improvements, there is still some noticeable overhead of a few seconds for some scripts i've written.

Same. I went down this road with GPT and was kinda disappointed TBH, since IIRC it recommended the language for the purpose.

I use ABS, Perl, PHP or Nim for most of that stuff but am always looking for new ones to try. (Preferably single binary these days since I have to migrate systems from time to time)

You can see some previous discussion on this at https://news.ycombinator.com/item?id=35477695 . I feel 1.9 would make it much more realistic. For CLI you can use https://comonicon.org/stable/ .
