For this option, together with the --search-paths option, would it be
possible to customize the syntax of the output from the
show-search-paths function? This might be a question for other guix
commands as well. Either the current shell or the shell from --exec
might set variables in a different way. E.g. the user is using the
"fish" shell, and doesn't want to spawn a new process, they should be
able to::
eval (guix environment --search-paths guile)
Btw, fish uses 'set -x PATH "..."' to export PATH set to "..."
Just a thought.

Could we instead have a -L or --load-path option like for `guix build`?
This would be useful if the user wants to give multiple packages to
`guix environment` that are all outside $GUIX_PACKAGE_PATH.
I'm very excited for this.
