Some users use `cpan -l` only to get information about installed Perl modules as part of system inquiries, but they do not use `cpan` for installing modules at all. I would like to ask whether configuring `cpan` is necessary when I am only interested in listing the modules. Or would it be possible to modify `cpan` so that in such cases, it skips the configuration, similar to how it works with `cpan -h`?
