representing graph in Clean

[khamenya]

Hello clean-list,

  (My questions deal with some general FP paradigm. I did not found
  answers in comp.lang.functional and that is why I feel free to sent
  these questions to clean-list. However Clean is my favorite
  functional language, why not send here?)

  Well, the questions are:

Q1: How to represent graph in Clean?
Q2: How to effectively represent graph in Clean?
Q2a: Can I access node Y which is neighbor for given node X at constant time?
Q2b: Is it possible to effectively represent graph in Clean _without_
     arrays?

thank you.
