-    If you look at the definition of `tree_walker` above, you'll see that its interface doesn't supply the `leaf_handler` function with any input like z; the `leaf_handler` only gets the content of each leaf to work on. Thus we're forced to make our `leaf_handler` return a function, that will get its `z` input later. (The strategy used here is like [[the strategy for reversing a list using fold_right in assignment2|assignment2_answers/#cps-reverse]].) Then the `joiner` function chains the results of handling the two branches together, so that when the seed `z` is supplied, we feed it first to `lh` and then the result of that to `rh`. The result of processing any tree then will be a function that expects a `z` argument. Finally, we supply the `z` argument that `tree_foldleft` was invoked with.

 5.  How would you use the function defined in problem 4 (the previous problem) to sum up the values labeling the leaves of an `(int) color_tree`?
