The iter argument to Container.Make says how to implement the container's iter function. `Define_using_fold means to define iter via:


        iter t ~f = Container.iter ~fold t ~f

`Custom overrides the default implementation, presumably with something more efficient. Several other functions returned by Container.Make are defined in terms of iter, so passing in a more efficient iter will improve their efficiency as well.
