NAME
       Perl::Critic::Policy::ValuesAndExpressions::ProhibitSpecialLiteralHeredocTerminator
       - Don't write " print <<'__END__' ".

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

DESCRIPTION
       Using one of Perl's special literals as a HEREDOC terminator could be
       confusing to tools that try to parse perl.

           print <<'__END__';           #not ok
           Hello world
           __END__

           print <<'__END_OF_WORLD__';  #ok
           Goodbye world!
           __END_OF_WORLD__

       The special literals that this policy prohibits are:

       __END__
       __DATA__
       __PACKAGE__
       __FILE__
       __LINE__

CONFIGURATION
       This Policy is not configurable except for the standard options.
