 =head1 FEATURE BUNDLES
 
 It's possible to load a whole slew of features in one go, using
 a I<feature bundle>. The name of a feature bundle is prefixed with
 a colon, to distinguish it from an actual feature. At present, the
 only feature bundle is C<use feature ":5.10">, which is equivalent
-to C<use feature qw(switch ~~ say err)>.
+to C<use feature qw(switch ~~ say err state)>.
