| /** |
| * @assertion An external function is a function whose body is provided |
| * separately from its declaration. An external function may be a top-level |
| * function, a method, a getter, a setter or a non-redirecting constructor. |
| * External functions are introduced via the built-in identifier external |
| * followed by the function signature. |
| * An external function is connected to its body by an implementation specific |
| * mechanism. Attempting to invoke an external function that has not been |
| * connected to its body will raise a NoSuchMethodError or some subclass |
| * thereof. |
| * @description Checks that invoking an external function that is not connected |
| * to its body indeed results in a NoSuchMethodError or its subclass being |
| * thrown. |
