       For legibility, HEREDOC terminators should be all UPPER CASE letters (and numbers), without any
       whitespace.  Conway also recommends using a standard prefix like "END_" but this policy doesn't enforce
       that.

         print <<'the End';  #not ok
         Hello World
         the End

         print <<'THE_END';  #ok
         Hello World
         THE_END

       Perl::Critic::Policy::ValuesAndExpressions::RequireUpperCaseHeredocTerminator - Write " <<'THE_END'; "
       instead of " <<'theEnd'; ".
