>>I'm looking for medium-scale examples of using function-generating
functions.
I'm not sure if this is exactly what you're looking for, but this sort of
thing is pretty cool:
(defn make-point [x y]
(fn [member]
(cond (= member :x) x
(= member :y) y)))
We're basically creating an immutable object without using a single data
structure:
(def pnt (make-point 1 2))
=> (pnt :x)
1
=> (pnt :y)
2
You can even get a bit more fancy:
(defn make-point [x y]
(fn [member]
(cond (= member :x) x
(= member :y) y
(= member :with-x)
(fn [newx]
(make-point newx y)))))
