What is Carp and confess in Perl?

Perl provides a module called Carp which is used for error handling. It is particularly useful because it helps to produce error messages that point to the location in the code where the error occurred. This is more user-friendly than standard Perl die messages, which might not indicate the exact place of failure.

Within the Carp module, the confess function issues a message that provides a backtrace of the call stack, indicating how the program arrived at the error point. It is particularly useful for debugging purposes.

Here is a simple example of how to use Carp and confess in your Perl code:

use Carp;
sub test_function {
confess("This is an error message!");
}

test_function();
