Yes, I would like these too -- the issue was raised in one of the
Extensions WG sessions but really got no support.

This has been discussed several times by the Extensions WG and the decision
was taken not to pursue this. I argued in favour of the extension because I
like nested functions but you can't win 'em all.
The closest you'll get is member functions of local classes, I think:
struct interface
{
virtual void function() const = 0;
};
void f(const interface& i)
{
// do stuff with i.function()
}
void g()
{
struct local : public interface
{
void function() const { ... }
};
f(local());
}

Something similar can be achieved with the using declaration:

using a::foo; // brings in all base class variants
// to overload foo(long)
