/**
 * @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
 * @author sgrekhov@unipro.ru
