Make `assert_difference` return the result of the yielded block.
With this we can perform new assertions on the returned value without having to cache it with an outer variable or wrapping all subsequent assertions inside the `assert_difference` block. Before: ``` post = nil assert_difference -> { Post.count }, 1 do Post.create end assert_predicate post, :persisted? ``` Now: ``` post = assert_difference -> { Post.count } do Post.create end assert_predicate post, :persisted? ```
