| * @assertion The type system is extended with a notion of a legacy type |
| * operator. For every type T, there is an additional type T* which is the |
| * legacy version of the type. There is no surface syntax for legacy types, and |
| * implementations should display the legacy type T* in the same way that they |
| * would display the type T, except in so far as it is useful to communicate to |
| * programmers for the purposes of error messages that the type originates in |
| * unmigrated code. |
| * |
| * @description Check that all fields of legacy type T* are nullable |
