Hi Simon,

I understand that one of the things you are trying to do is to have a
common interface for the cache and no-cache cases. To achieve this, I
think fold-available-packages and fold-packages should have the same
function signature. They should both pass a <package> object to
PROC. Currently, fold-packages is passing a <package> object whereas
fold-available-packages is passing the fields of the <package> object as
individual parameters. If fold-packages and fold-available-packages have
the same function signature, then the changes in your [PATCH v6 2/2]
would be way simpler.

Also, why do we need two separate functions---fold-available-packages
and fold-packages? Can't fold-available-packages do everything
fold-packages can and thus totally replace it?

A couple of typos here:

find-packages-by-names -> find-packages-by-name
find-packages-locations -> find-package-locations
