Although I haven't tested it, I think CountZero's approach avoids dupes: splice removes each spliced element from the  @choices source array before the next pick. I like CountZero's approach better because it's simple, doesn't depend on a module, and seems like it would scale well to very large arrays. The only drawback I see is that the source array is mutated. However, I believe there is a large literature base on 'fair' picking, so there's probably an even better solution!
