Initially, I thought the same as Ludo: "run-script" should be an
option to "repl". And I understand your UI concerns.

Maybe, we could deprecated "repl" and add "run" with:
 - guix run <file> (same than the "guix run-script" proposal)
 - guix run or guix run --repl doing the what "guix repl" does.

The new command "guix run" could have more or less the same option
than "guile" but prepending all the paths correctly. I mean we need
something like "guix name-it <otpions>" mimicking "guile <options>"
adding the correct Guix modules, IMHO.

BTW, thank you for this. Because it was missing in my toolbox and I
was annoyed until now.
