 * Iteration is done a bit differently. In Ruby, you don’t use a separate
-  iterator object (like `vector<T>::const_iterator iter`) but instead
-  your objects may mixin the `Enumerator` module and just make a method
-  call like `my_obj.each`.
+  iterator object (like `vector<T>::const_iterator iter`).
+  Instead you use an iterator method of the container object (like `each`)

 * There’s only two container types: `Array` and `Hash`.
 * There’s no type conversions. With Ruby though, you’ll probably find
   that they aren’t necessary.
