In Eiffel, DbC works with inheritance. So a subclass is bound to
the same contract as its parent class automatically. Not being
an Ada guru, I'd guess you would have to copy the parent's
contract into the child, leading to undesirable duplication.

I don't have a short answer to that. Best I can say is read the
relevant chapters in Meyer's "Object Oriented Software
Construction" (2nd Ed.)
