*cool* is in the eye of the beholder, worthy monk:

$ corelist Data::Dumper

Data for 2017-01-14
Data::Dumper was first released with perl 5.005

$ corelist Data::Dump

Data for 2017-01-14
Data::Dump was not in CORE (or so I think)

[download]

To some, "cool" is working without non-core modules, not necessarily what's newer or more fashionable. I'm not saying that Data::Dump is bad, I'm just pointing out that Data::Dumper is available with almost any Perl 5 install.
