You can already do this with guix shell or gwl if you prefer.
To elaborate, note that only the last variable in a file or manifest needs to evaluate to a list of packages or manifest. That is, you can write a self-reading manifest/script wrapper relatively easy. #!/bin/sh exec guix shell -m "$0" -- guile -e main -s "$0" "$@" !# (define (main args) ...) ... (specifications->manifest ...) Of course, it'd be hell of a lot cleaner to separate manifest and business logic, but who am I to stop you? Cheers
