Mixing implementations and interfaces is such a bad idea. I try to avoid these and aspects and even "is null" implementations. I recently discovered yet another reason. When building an encapsulated library, shoveling implementations inside the specification breaks the library interface because implementation packages must with-ed there. When with-ed from the bodies, as it should be, the library interface includes only what it really must. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
