Indeed.  ;-)

I can sympathize with this.

I think ‘specification->package’ from (gnu packages) is the procedure
you want.  Like this:

  (map specification->package
       '("guile-2" "gnupg-2.0" "coreutils"))

It emits a warning in case the specification is ambiguous.

Maybe we could/should use it in the example GuixSD configurations, and
at least document it somewhere.

WDYT?

Thanks,
