Perl::Critic::Policy::ValuesAndExpressions::RequireQuotedHeredocTerminator − Write " print <<'THE_END' " or " print <<"THE_END" ".
This Policy is part of the core Perl::Critic distribution.
Putting single or double-quotes around your HEREDOC terminator make it obvious to the reader whether the content is going to be interpolated or not.
print <<END_MESSAGE; #not ok Hello World END_MESSAGE print <<'END_MESSAGE'; #ok Hello World END_MESSAGE print <<"END_MESSAGE"; #ok $greeting END_MESSAGE
This Policy is not configurable except for the standard options.
