Cool, thanks Rich! This will be fun to play with. One question -- is it possible to get the previous value of the agent (before the action) from within the callback fn? I noticed this -- if a callback throws an exception, the agent stops accepting messages, but agent-errors remains empty: user=> (def a1 (agent 1)) user=> @a1 1 user=> (add-watch a1 :dumb (fn [w a c] (eval 'missing-var))) user=> (send a1 (fn [a] 2)) user=> @a1 2 user=> (send a1 (fn [a] 3)) user=> @a1 2 ;; The last action didn't run user=> (agent-errors a1) nil -Stuart --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
