protocol _DestructorSafeContainer A container is destructor safe if whether it may store to memory on destruction only depends on its type parameters. For example, whether Array<T> may store to memory on destruction depends only on T. If T is an Int we know the Array<Int> does not store to memory during destruction. If T is an arbitrary class Array<MemoryUnsafeDestructorClass> then the compiler will deduce may store to memory on destruction because MemoryUnsafeDestructorClass' destructor may store to memory on destruction.
