AK> I suppose the error is in the over.over.

I fail to see the problem. 5.3.1 (which you quote correctly) says that
&X::f could be a pointer to member, but not &(X::f); so that explains
the error in 13.4. &(X::f) resolves to the pointer to a static member
function (which is a pointer to a regular function) in that same
example, so that's fine. Note that the target type resolves the overload.
