While it's not germane to Martin's point, this code is illegal in Ada 200Y:
a null procedure cannot be a completion. Why not? Null procedures are
similar to abstract subprograms in use and description, and those clearly
can't be a completion. And it didn't seem worth a new bunch of rules to
avoid typing 12 characters - the least important savings that one could
imagine.
