Interestingly we use such a routine in Haskore for splitting a sequence of notes into sequences of notes of equal instruments. It's implemented rather the same way like your version. It's 'slice' in http://darcs.haskell.org/haskore/src/Haskore/Basic/TimeOrderedList.lhs but it is a bit more complicated because it has to manage time information. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
