| /// 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. |
