What about something like CGI::Carp? Is this not in the contemporary core? 
$ corelist CGI::Carp

Data for 2022-12-20
CGI::Carp was first released with perl 5.004, deprecated (will be CPAN
+-only) in v5.19.7 and removed from v5.21.0
$

[download]

So that's a pretty definitive "no".

Note that none of the other alternatives you have mentioned are in core either, which is fine by me. Just download what you want to use and then use it - don't worry about what is bundled in.
