You want this to work with multiple module versions side by side. We
have a disk namespace where we put every module version in its own
directory, and the user can choose which version is required by
specifying 'use lib'. When a new version comes out, we install it
without touching the existing files - which makes backing out an
upgrade very easy.
If multiple versions of a module could co-exist in the same program,
e.g. by extending the namespace by the module version number, that
would solve some issues in e.g. mod_perl, or in Storable release x ->
x+1 migration scripts.
