My first feeling was that this would be illegal, but I could not find anything
in the standard supporting this feeling. F03 only has the following
restrictions:

C427 (R429) If the type definition contains or inherits (4.5.6.1) a
deferred binding (4.5.4), ABSTRACT shall appear.

C428(R429) If ABSTRACT appears, the type shall be extensible.
