 * 2.0.next in progress
+  * Address [#26](https://github.com/clojure-expectations/clojure-test/issues/26) by adding an example combining `more->` and `more-of` around destructuring `ex-info` data.
   * Fix [#24](https://github.com/clojure-expectations/clojure-test/issues/24) by using a local (gensym) for the actual value in `more` and `more->` so it is only evaluated once.
   * Update `build-clj` to v0.6.7 and automate snapshot/release builds.

 Although this is more verbose for this basic example, remember that the
 `expected` value could also be a predicate function, a regex, a Spec, etc.
 
+`more-of` can also be used with `more->` to provide succinct tests on Clojure's `ex-info` exceptions:

+```clojure

+```
+
+In this example, the exception is threaded into `type` and the predicate is a class, and it is also threaded into `ex-data` and the predicate is a `more-of` expression that destructures that data and matches parts of it.
