What does reabstraction mean?

[Chance Gold]

Heh, the weak model does create another "hope that's okay" possibility per
Brian's examples, but I was bothered by this one aspect in the December
State of the Lambda discussion of Default methods, which I believe
specified the strong model. I think satisfaction of a default none method
by a 'coincidental method' - i.e. matching in signature, would be more
appropriate as a compiler warning.
