For example, if your state were a vector [:x :o :x nil .... :x] (for a board of tic-tac-toe), calling (assoc board 3 :x) will return a new board with the position 3 set to :x.
Yes but in tic-tac-toe you are inserting pieces while in chess/checkers you move pieces...that is, pieces disappear from their original position and move to the next. Using your recommendation I would have to do at least 1 dissoc and 1 assoc for a single move won't I? on the other hand, with your approach it means I don't have to build a new board after each move - it happens automatically...
by the way, and I'm not trying to argue here...trying to make constructive conversation! I don't have a lot of people I can talk with about these things...thanks :-)
