Overriding property setters

Is there a way to provide an alternate function binding for property
setters?

(please excuse the abbreviated pseudocode)
I would like to do something like this in Lua:

Obj.Position = Vector(0,10,0);
Obj.Position = Velocity(Vector(0,0,-15));

In the c++:
_class<Object>
[
   .property("Position", &Object::getPosition, &Object::setPosition)
]

class Velocity: public MovementPolicy
{ // details about moving at a constant velocity.
}

Vector Object::getPositon()
{ // return my position
}

Object::setPosition(const Vector &pos)
{ // set my position
}

Object::setPosition(const MovementPolicy *pPolicy)
{ // do the stuff that will move my position every frame.
}
