You'll need to update your version of Instaparse as well. This issue comes because Instaparse has a function called "cat" in one of its namespaces, and Clojure 1.7 introduces a function call "cat" in the core namespace. Clojure's delivers a warning when you override a function a function from another namespace.
For example, I could have a namespace like: (ns example.core) (defn cat [x] (str x " says meow")) This would work fine on earlier versions of Clojure, but from 1.7 onward, Clojure would complain because "example.core/cat" conflicts with "clojure.core/cat". To fix this, I can add in: (ns example.core (:refer-clojure :exclude [cat])) (defn cat [x] (str x " says meow")) This namespace will load without errors, because we're explicitly told Clojure we don't want to refer to clojure.core/cat in the current namespace. Later versions of Instaparse add this exclusion in, fixing the warning. - James On 13 July 2016 at 12:32, Cecil Westerhof <cldwester...@gmail.com> wrote: > I want to pick up Clojure again.
