Note that the Nullable is not phobos Nullable -

In Bugzilla I have suggested some improvements for Nullable,
but in Phobos there is already an alternative Nullable that
avoids that overhead:
struct Nullable(T, T nullValue);

The question is what should be the result of:
Nullable(int*)?
New type, but no overhead.
Nullable!(Nullable!T)?
New type, with an extra boolean.
