Re^4: Can't find a tree in the forest - CPAN and AddHistory

[Wiggins]

OK; So I need some education about what "core" means to Perl.
I assume 'core' packages are those that are present when the Perl system is initially installed on the OS. Not something that takes an ancillary/subsequent install.
This system already had Perl and CPAN installed; so that would have done a 2nd install of some of the 'core' packages? And then a subsequent refreshing/upgrading of CPAN will do a 3rd install (if needed)?
So why is Term::ReadLine a "core" package? What am I missing?

[Corion]

Term::ReadLine is distributed with Perl in whatever version is current. So far, the distribution mechanisms of Perl have not yet advanced to the state where a version can always be distributed that will be current in the future. So, as a workaround, intermediate releases of many such modules are done via CPAN so you can upgrade core modules to more current versions even though you don't upgrade your version of Perl.
