+** pos_set_set
+The current approach is correct, but with poor performances.  Bitsets need
+to support 'assign' and 'shift'.  And instead of extending POS_SET just for
+the out-of-range new values, we need something like doubling the size.
+
 ** YY_LOCATION_PRINT
 This is an internal detail.  But it's very handy, we should make it public.
 It already has leaked in the documentation by accident.
