I don't have my own examples, anyway being a daily object-oriented
programmer I'm feeling compelled to say that where function-generating
functions prove their main practical power is in what I'd label man in
the middle functions.
Whenever I need to add behaviour to an existing OO method I have
typo, I meant ring *middleware*, not ring handlers

Brian, when I saw this I was reminded of ring middleware - eg.

How about the new reducers library:

While admittedly neat, and educational, this kind of code is fancy for
production use in my opinion:
(defn make-point [x y]
(fn [member]
(cond (= member :x) x
(= member :y) y)))

I think enlives transformersare a very good example of functions returning
functions. Maybe you should have a look at the getting started guide and
the tutorials

I'm not sure if this is exactly what you're looking for, but this sort of

We're basically creating
trampolines is a slightly different example.

Maybe SICP's simulator of digital circuits will provide some inspiration. I
know when I read this I was deeply awed by what HOFs can do. Maybe
Clojure's zippers would be good too?
