in reply to Promoting Text::CSV to base Perl?
The people to lobby for that would be the Perl5-Porters. One problem that Perl faces is that the continous maintenance of things in the Perl core puts a burden on the Perl developers, hence they are not keen on taking on things that can be installed from CPAN or your distribution package manager instead.
Installing modules for the current user has also become much easier, and there is at least talk of actually getting (something like) local::lib into the Perl core. This would make locally installing modules much easier.
If you are a developer, or a person writing Perl code, you should also be able to download the two .pm files from CPAN, as Text::CSV does not need any external dependencies beyond what comes with Perl.
