Hi Ambrose, Thanks for the advice. I have already implemented my application using maps (defstruct) and busy evaluating whether I should switch to records. I like the idea of using records and protocols to help me to define strict abstractions and to do easy type dispatch. On the other hand I can see that they reduce flexibility. I will post some code to show what I am trying to do...
