/// @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.
