Internal Program Version: perl-carp-clan  6.80.0.5.42.0

This module is based on 'Carp.pm' from Perl 5.005_03. It has been
modified to skip all package names matching the pattern given in the "use"
statement inside the 'qw()' term (or argument list).

Suppose you have a family of modules or classes named "Pack::A", "Pack::B"
and so on, and each of them uses 'Carp::Clan qw(^Pack::);' (or at least
the one in which the error or warning gets raised).
