(let [pred #(exists? ".foo")] (wait-until pred)) ;; <- the fact that it's called 'pred is not interesting in most cases > The trade-off is breaking an existing public API. > How so? (defmacro op [msg args expr] `(with-meta (fn ~args ~expr) {:msg ~msg :args '~args :expr '~expr})) (let [pred1 #(exists? ".foo") pred2 (op "checks existance" [] (exists? ".foo"))] ;; both these will work, the one with pred1 will give less useful errors. the API of wait-until is unchanged (wait-until pred1) (wait-until pred2)) If Shalaka's primary goal is prettier errors in test failures, I'd settle > for the fn body itself as the error message and that could be achieved > without breaking the API. > The op macro can include the code in its information. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
