Perl::Critic::Policy::ValuesAndExpressions::RequireUpperCaseHeredocTerminator - Write <<'THE_END'; instead of <<'theEnd'; .
This Policy is part of the core Perl::Critic distribution.
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
print <<'THE_END'; #ok
This Policy is not configurable except for the standard options.
