No. The reason is the implementation may be in another .obj file known
only to the linker.
I can't see how that makes sense, even with the above (un-idiomatic?)
idea. The compiler should not emit references to *abstract* methods.
I think this looks like a case of class attributes not affecting methods:
"Address" is declared as an abstract class, but the compiler doesn't
realize that its methods are abstract too. They are simply declared as
method declarations without a body.
This is similar to another old bug (now fixed, I believe), when methods of
"final" classes were still implicitly virtual.
