Answer 1

It's not quite what you asked for, and it's not directly related to Haskell, but Bruce McAdam's paper That About Wraps It Up goes into this topic in substantial breadth and depth. Bruce's basic idea is to use an explicit knot-tying operator called WRAP instead of the implicit knot-tying that is done automatically in Haskell, OCaml, and some other languages. The paper has lots of entertaining examples, and if you are interested in knot-tying I think you will come away with a much better feel for the process.
