Hello! When I set the :warning-handlers key in project.clj (as explained here: https://github.com/emezeske/lein-cljsbuild/blob/master/README.md#custom-warning-handlers), I get the following exception

clojure.lang.ArityException: Wrong number of args (3) passed to: Symbol

I'm using

:warning-handlers [my-project.build/warning-handler]

It looks like cljsbuild uses the namespaced symbol as the warning handler, not the function referenced by the symbol
