| * @assertion Any expression of the form e1(args) or e1<types>(args) where e1 |
| * does not denote a method, and where the static type of e1 is not a function |
| * type, an interface type declaring a call method, or dynamic, will currently |
| * be a compile-time error. If the static type of e1 is an interface type |
| * declaring a call getter, then this stays a compile-time error. Otherwise we |
| * check for extensions applying to the static type of e1 and declaring a call |
| * member. If one such most specific extension exists, and it declares a call |
| * extension method, then the expression is equivalent to e1.call(args) or |
| * e1.call<typeS>(args). Otherwise it is still a compile-time error. |
| * |
| * @description Check that it is a compile error if there is no most specific |
| * extension with the call method |
