Hello Alistair, Friday, May 16, 2008, 2:12:45 PM, you wrote:
concatM = liftM concat . sequence
but found no such thing in the std libs, except perhaps for msum (I don't want to add instances for MonadPlus. Should I have to?). Have I missed something trivial?
1. it's easy to define yourself 2. it's not widely used. at least, i have in my program for, foreach, concatMapM, filterM and lot of other monadic operations, but no one concatM -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
