I know. I am a long-time fan of your Perl work. And I know how to get them dynamically via an API which is done for example in https://metacpan.org/pod/Devel::Trepan::Deparse https://metacpan.org/pod/Devel::Trepan::Deparse What I don't know how to do, if you could help is register in Perl that I want my routine called when Perl hits an error, so that I can do the deparse and spit out a more detailed location message. Thanks!
