Well, since your definition of "correclty" is uknown, I won't use
it. I will point out that the stated goal is impossible for some
reasonable definitions of "correctly".

My definition of "correctly" is "meets the published contracts for the
methods."  Languages with good support for design by contract will
insure that subclasses either correctly implement the published
contracts, or raise an exception when they fail to do so. They do that
by checking the contracts for the super classes in an appropriate
logical relationship, and raising an exception if the contract isn't
met.
