+It could be good, or not.
+One point about it is that this form does not explicitly specify the
+order of the iteration.  Therefore I would only use it in cases where
+that is the intent, and even in that case, explicitly specify the type.
+<code>
+int main() {
+  int numberArray[] = {
+,
+,
+,
+,
+  };
+  for (int number: numberArray) {
+    cout << number << " ";
+  }
+  return 0;
+}
+</code>
+prints: 100 200 300 400 500
+....  or does it?
+why not: 300 200 500 400 100
+....  ?
+We really need a loop like this, or better yet .. one that supports
+parallel operation.  This would have been a good place to introduce it.
