I'd like to push out biocore 0.3 with classes and stuff (as well as some dependent packages), but we need to resolve this first. We have several alternatives here: slice :: s -> Offset -> Offset -> s -- start and end, inclusive or exclusive slice :: s -> Offset -> Offset -> s -- start and length slice :: s -> Offset -> Int -> s -- start and length, but different types Then there's the standard set of chopping operators, with and without predicates: take, drop, span, takeWhile, etc. And vector supports unsafeSlice for speed. My current sentiment is to drop this for now, the design space is pretty cluttered, and it's probably easier to add stuff later than to take it out. Thoughts? -k -- If I haven't seen further, it is by standing in the footprints of giants _______________________________________________ Biohaskell mailing list Biohaskell@biohaskell.org http://malde.org/cgi-bin/mailman/listinfo/biohaskell
