I figured, but had to ask. I'm looking into adding a feature to Midje to be able to say:
(defn g [a b c d e f g] nil) (fact (f 1) => 1 (provided (g ...) :never )) instead of what you currently have to say for the equivalent: (fact (f 1) => 1 (provided (g anything anything anything anything anything anything anything) => anything :never )) Knowing the arity of the function would have helped with the internals.
