       Perl::Critic::Policy::ErrorHandling::RequireCarping - Use functions from Carp instead of
       "warn" or "die".


       This Policy is part of the core Perl::Critic distribution.


       The "die" and "warn" functions both report the file and line number where the exception
       occurred.  But if someone else is using your subroutine, they usually don't care where
       your code blew up.  Instead, they want to know where their code invoked the subroutine.
       The Carp module provides alternative methods that report the exception from the caller's
       file and line number.

       By default, this policy will not complain about "die" or "warn", if it can determine that
       the message will always result in a terminal newline.  Since perl suppresses file names
       and line numbers in this situation, it is assumed that no stack traces are desired either
       and none of the Carp functions are necessary.

           die "oops" if $explosion;             #not ok
           warn "Where? Where?!" if $tiger;      #not ok

           open my $mouth, '<', 'food'
               or die 'of starvation';           #not ok

           if (! $dentist_appointment) {
               warn "You have bad breath!\n";    #ok

           die "$clock not set.\n" if $no_time;  #ok

           my $message = "$clock not set.\n";
           die $message if $no_time;             #not ok, not obvious


       By default, this policy allows uses of "die" and "warn" ending in an explicit newline. If
       you give this policy an "allow_messages_ending_with_newlines" option in your .perlcriticrc
       with a false value, then this policy will prohibit such uses.

           allow_messages_ending_with_newlines = 0

       If you give this policy an "allow_in_main_unless_in_subroutine" option in your
       .perlcriticrc with a true value, then this policy will allow "die" and "warn" in name
       space main:: unless they appear in a subroutine, even if they do not end in an explicit

           allow_in_main_unless_in_subroutine = 1


       Should allow "die" when it is obvious that the "message" is a reference.
