Finally, we can do the same thing as the las refactor but with a little bit less code if we take advantage of [Enumerable#any?](http://ruby-doc.org/core-2.1.2/Enumerable.html#method-i-any-3F).

```ruby
def contains_point?(x, y)
  rects.any? do |rect|
    rect.contains_point?(x,y)
  end
end
```

So if the block returns true for any of the iterations, the return value will be true.
