Keep in mind too that since test.check/quick-check takes a property as an
argument, you can construct a property by simply closing over some
implementation. For example:
(defn make-prop
[impl]
(prop/for-all [...]
(= (impl ...) (other ...)))
And then test with different properties created with (make-prop ...).
