Credit where credit is due, the shebang's idea comes from guix's manual.
You can also do the following:
#+begin_src bash
#!/usr/bin/env bash
# Autowrap self in guix shell
if [ -z "${GUIX_ENVIRONMENT:-}" ]
then
guix shell YOUR DEPENDENCIES HERE -- "$0" "$@"
exit 0
fi
ACTUAL CONTENTS OF THE SCRIPT HERE
#+end_src
Cheers !
Edouard
