I would further your reasoning on tolerance: it depends on whether the key, the map or both are variable. (key map) is safe as long as you know that key is a symbol or a keyword. (map key) is safe as long as you know that map will not be nil. (get map key) never fails ((get (Object.) (Object.)) returns nil) Christophe -- Professional: http://cgrand.net/ (fr) On Clojure: http://clj-me.blogspot.com/ (en) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
