I took a shot at packaging bettercap[1] this weekend but decided to
finish it later after realizing how many dependencies would need to be
packaged... Ah, how I long for a 'go' importer.

But since we're having this conversation now, I'd like to ask: does it
make sense to use 'define-public' for dependencies like that? I'd be
adding a lot of 'go-github-com-...' packages like those in
'gnu/packages/syncthing.scm'.
