     47Within icGrep 1.0, the MatchStar primitive elegantly handles Kleeene-* repetitions
     48of character classes (e.g. [a-z]*) using a single long-stream addition operation
     49together with bitwise logic.   Other Kleene-* repetitions are currently handled
     50using while loops, but it is known that the MatchStar technique can be adapted
     51to apply in some cases.  Codifying and extending these techniques is an important
     52area for algorithmic work.
