 * The ?-quantifier on captures in regexes currently binds the capture
   slot to a List containing either zero or one Match objects; i.e., it
   is equivalent to "** 0..1".  In the future, the ?-quantifier will
   bind the slot directly to a captured Match or to Nil.  Existing code
   can manage the transition by changing existing ?-quantifiers to
   use "** 0..1", which will continue to return a List of matches.
