When doing this sort of investigation, I find the core utility corelist to be very useful. This has a number of options; here's a selection of examples:
Note that some modules have been added then removed from core:
If it's important to you, perlhist gives the date of Perl releases. Modules which are core, but do not have a separate CPAN version, will show perl-<version> as the distribution when you search for them using MetaCPAN; for instance, "MetaCPAN: File::Copy" gives: Ricardo SIGNES / perl-5.36.0 / File::Copy On the left-hand panel, under TOOLS, the Download link points to the tarball: 'https://cpan.metacpan.org/authors/id/R/RJ/RJBS/perl-5.36.0.tar.gz'. You can't install this module separately from CPAN. Modules which are core, but also have a separate CPAN version, show a distribution which is not perl-<version>; it may reflect the module name, e.g. Some-Module-<version>, or it may be part of a bundle of modules under a different name, e.g. Various-Modules-<version>. For instance:
From "MetaCPAN: List::Util": Paul Evans / Scalar-List-Utils-1.63 / List::Util The distribution name is a link. Follow this to get additional information, including a list of bundled modules. Also under TOOLS (left-hand panel) there's a "Jump to version" dropdown list: possibly useful if you want to install an older version from CPAN. — Ken
