| /// @assertion A static member invocation still only works on an uninstantiated |
| /// type literal. You can write List.copyRange, but not List<int>.copyRange. |
| /// |
| /// Allowing List<int>.copyRange is confusing. The invocation will not have |
| /// access to the type parameter anyway, so allowing it is not going to help |
| /// anyone. The occurrence of List in List.copyRange refers to the class |
| /// declaration, treated as a namespace, not the class itself. |
| /// |
| /// This goes for type aliases too. We can declare typedef MyList<T> = List<T>; |
| /// and typedef IntList = List<int>; and do MyList.copyRange or |
| /// IntList.copyRange to access the static member of the declaration of the type |
| /// being aliased. This is specially introduced semantics for aliases of class |
| /// or mixin types, not something that falls out of first resolving the type |
| /// alias to the class or mixin type. We do not allow MyList<int>.copyRange |
| /// either, even though we allow IntList.copyRange. They are not the same when |
| /// doing static member accesses. |
