       i tried making a version that stores the results of (self.f)(k) in an internal Vec but you run into mutability/lifetime issues and i don't think it's possible without UnsafeCell or something like it :(

       @hierarchon I've never written a line of rust and I'm trying to understand this. Is it an obtuse way of determining if a number is even or odd by overloading the methods of a data structure? Are pointers involved?

       @nleigh Rust lets you define what it means for a data type to be indexed like `foo[bar]`, so I'm constructing a new data type that just wraps a function and invoking that function to 'index' into it.
