Oops, it's not fixed, I entered the wrong number.

It's invalid. The request is for contravariance of parameter types, and this
will not work in the general case because of function overloading and
overriding (which rely on exact matching of parameter types). Making it work in
a specific case is a kludge and will cause all kinds of problems in the future.

It's an attractive idea, but it's been considered and rejected a couple of
times now.
