And if we check: `(\n b. n a) (\a. \n b. n a) b ~~>` `(\b. (\a. \n b. n a) a) b ~~>` `(\b. (\n b. n a)) b ~~>` -`(\n b. n a)` ≡ +`(\n b. n a) <~~>` `m a` Looks good. So `f` needs to be a function that accepts an argument `w` (after the first stage, this will be `m a`), and an argument `b`, and applies `w` to `m` and to `b`. In other words, `f` should be:
