Overview

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.
