To get the absolute best performance of the platform without having the pollute your code with type information. For example prior to 1.2 I had to use javax.vecmath.Vector2D and litter my functions with type-hints. Now I can just use a library like cantor (http://github.com/ztellman/cantor), get the exact same perf, and not have to think about putting type information anywhere. > One thing that lisp got absolutely right is the unification of the symbol > nil, the empty list (), and the boolean "false".

I haven't seen many cases where this is a problem in practice. (doall (map inc nil)) (doall (map inc [])) -- You received this message because you are subscribed to the Google Groups "Clojure" group.
