Hello Guix!

I'd like to implement something similar to NixOS's command-not-found in
Guix.
As you can see in the repository below, it contains a nix file which is
essentially a shell script which runs the second file, a perl script, if
the user enters a command which is not found on this system. The perl
script suggests names of packages containing said command which it pulls
from an SQL database.
https://github.com/NixOS/nixpkgs/tree/master/nixos/modules/programs/command-not-found
This would make Guix much more user-friendly; for example, new Guix System
users often struggle to figure out how to add the "clear" command to their
shell. command-not-found would immediately inform them that it can be found
in the ncurses package.

How would you recommend I go about implementing something similar for Guix?
I have unfortunately been unable to find a database or anything similar
listing files outputted to /bin by each package, which would in my opinion
be the starting step.

Happy Hacking!
