Use "an" before "i32" (Minor typo fix.) Since the word `i32` starts with a vowel, the indefinite article should use "an", not "a" \[[1](http://www.dictionary.com/browse/an)\]. (Previously there was one instance of "an i32" and two instances of "a i32", so at least something is wrong!) Since I believe that "an" is the correct form, I aligned everything with that.

Because `Fn` is a trait, we can use it as a bound for our generic type. In
