Hello, Evaluating the form (let [cache (atom {})] (defmacro eval-cached "Just as eval, however it will return an existing object if it has already been evaluated with it" [obj] (when-not (contains? @cache obj) (reset! cache (assoc @cache obj (eval obj)))) (@cache obj)) (defmacro def-cached "Just as def, however it will return an existing object if it has already been defined with it" [fname fbody] (intern *ns* (symbol fname) (eval-cached fbody))))
Gives me a java.lang.UnsupportedOperationException: Can't eval locals - for the last line of "def-cached" However, when I use eval the first defmacro by itself as a closure - it works perfectly. How can I make those share the cache state without binding it to a public symbol ?
