Perl::Critic::Policy::Documentation::RequireEndBeforeLastPod - require __END__ before POD at end of file
This policy is part of the Perl::Critic::Pulp add-on. It requires that you put an __END__ before POD which is at the end of a file. For example,
__END__ # good
and not merely
1; # bad
This is primarily a matter of personal preference, so the policy is low severity and only under the "cosmetic" theme (see "POLICY THEMES" in Perl::Critic). An __END__ like this has no effect on execution, but it's a fairly common convention since it's a good human indication you mean the code to end there, and it stops Perl parsing through the POD which may save a few nanoseconds.
This policy is looser than Documentation::RequirePodAtEnd. This policy allows POD to be anywhere in among the code, the requirement is only that if the file ends with POD then you should have an __END__ between the last code and last POD.
A file of all POD, or all code, or which ends with code, is ok. Ending with code is usual if you write your POD at the start of the file or in among the functions etc,
And that's all.
exit 0; # good
A file using __DATA__ is always ok, since you can't have __END__ followed by __DATA__, wherever you want your POD. If the __DATA__ is in fact SelfLoader code then it can helpfully have an __END__ within it, but as of perlcritic version 1.092 no checks at all are applied to SelfLoader sections.
As always if you don't care about __END__ you can disable RequireEndBeforeLastPod from your .perlcriticrc in the usual way (see "CONFIGURATION" in Perl::Critic),
