+
+The pragma doesn't apply when one dereferences the returned value of an array or hash slice, as in C<< @array[$id]->{member} >> or C<< @hash{$key}->{member} >>.
+This syntax is valid Perl, yet it's discouraged as the slice is here useless since the dereferencing enforces scalar context.
+If warnings are turned on, Perl will complain about one-element slices.
