env, -l and command line arguments

[Formbi]

Hi

I'd like to make a script and be able to jump into the REPL if needed (for 
example if «--repl» is not passed, «(exit)» is run). I also run Guile through 
env -S, because I'm on Guix and I wanna make the script portable.

However, I can't find an easy way to do it. When I use «-l» and pass some 
command-line arguments to the script, Guile crashes because it interprets the 
arguments as files to load. When I use «-l --», it crashes because it can't 
find the «--» file. When I use «-- -l», it doesn't load the file. Even weirder 
to me is the fact that if I just put «(exit)» in the script, Guile doesn't 
crash.

I kinda managed to get the REPL functionality using some Bash shenanigans made 
by someone else, but shouldn't there be an easier way? Or does it exist, but I 
haven't stumbled upon it?
