The cluck Function in Perl
The cluck function in Perl is a sort of supercharged carp, it follows the same basic principle but also prints a stack trace of all the modules that led to the function being called, including the information on the original script.
package T; require Exporter; @ISA = qw/Exporter/; @EXPORT = qw/function/; use Carp qw(cluck); sub function { cluck "Error in module!"; } 1;
When called from a script like below −
use T; function();
It will produce the following result −
Error in module! at T.pm line 9 T::function() called at test.pl line 4
