Perl::Critic::Policy::ValuesAndExpressions::RequireQuotedHeredocTerminator(3) User Contributed Perl Documentation Perl::Critic::Policy::ValuesAndExpressions::RequireQuotedHeredocTerminator(3)

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.
