9 The "die" and "warn" functions both report the file and line number
10 where the exception occurred. But if someone else is using your sub‐
11 routine, they usually don't care where your code blew up. Instead,
12 they want to know where their code invoked the subroutine. The Carp
13 module provides alternative methods that report the exception from the
14 caller's file and line number.
15
16 By default, this policy will not complain about "die" or "warn", if it
17 can determine that the message will always result in a terminal new‐
18 line. Since perl suppresses file names and line numbers in this situa‐
19 tion, it is assumed that no stack traces are desired either and none of
20 the Carp functions are necessary.

23 warn "Where? Where?!" if $tiger; #not ok

25 open my $mouth, '<', 'food'
26 or die 'of starvation'; #not ok
27
28 if (! $dentist_appointment) {
29 warn "You have bad breath!\n"; #ok
30 }
31
32 die "$clock not set.\n" if $no_time; #ok
33
34 my $message = "$clock not set.\n";
35 die $message if $no_time; #not ok, not obvious
36
37 If you give this policy an "allow_messages_ending_with_newlines" option
38 in your .perlcriticrc with a false value, then this policy will disal‐
39 low all uses of "die" and "warn".
