1. In terms of Haskell, Judy is a library of _mutable_ collections of _unboxed_ elements. i pointed you to the Array wiki page, where differences between boxed and unboxed, mutable and immutable datastructures are described

There's no reason you can't use Judy to implement immutable collections, just as we use mutable arrays to implement immutable ones. Cheers, Simon
