 This generates a compile-time error if you access a variable that wasn't
-localized via C<my()> or wasn't fully qualified.  Because this is to avoid
+declared via "our" or C<use vars>,
+localized via C<my()>, or wasn't fully qualified.  Because this is to avoid
 variable suicide problems and subtle dynamic scoping issues, a merely
 local() variable isn't good enough.  See L<perlfunc/my> and
 L<perlfunc/local>.
