interpreter - app not working.

[jiegao1977]

When I use m/app in rewriter, the first one is working:

(let [s (i/rewriter '{:a ?a, :b ?b, :c ?c}
'{:c {:a1 ?a, :b1 ?b, :c-plus (m/app inc ?c)}})]
(s {:a 100 :b 200 :c 100}))

But below items not work, when there are 2 partakers to i/app.

(let [s (i/rewriter '{:a ?a, :b ?b, :c ?c}
'{:c {:a1 ?a, :b1 ?b, :c-plus (m/app * ?a ?b)}})]
(s {:a 100 :b 200 :c 100}))
