This looks neat!

The (system ffi) module looks interesting. It would be nice to
integrate some of these ideas it into Guile proper eventually.

Cool. Just one nit: #$ is also used by Guix, so it would be nice if
guile-bash would use something else, in the interest of composability.
;-)
Random comments:
• lisp/ is conventionally the directory containing elisp code; for
Guile code, some of us use module/ or modules/ or just the
top-level directory.
• There are places with unnecessarily repeated #:export or
‘use-modules’ forms that look verbose to me.
Thanks for the nice hack!
