   There are several cases where it's useful to spec (and generate) values in a range and spec provides helpers for these cases.
   
  -For example, in the case of a range of integer values (for example, a bowling roll), use https://clojure.github.io/clojure/branch-master/clojure.spec-api.html#clojure.spec.gen/int-in[`int-in`] to spec a range (end is exclusive):

  To redefine our spec using this custom generator, use https://clojure.github.io/clojure/branch-master/clojure.spec-api.html#clojure.spec.gen/with-gen[`with-gen`] which takes a spec and a replacement generator:
