This algorithm seems not effective, length, take, drop and (!!) are costly. Is there any better way to implement shuffle?
You can use mutable arrays (modules Data.Array.MArray, Data.Array.IO).
But is that better, really? IIUC, you will now need to shift the first part of the string to the right, so it's still a linear operation for each shuffle. -kzm -- If I haven't seen further, it is by standing in the footprints of giants
