C = new Object();
B = new Object();  B.__proto__ = C;
A = new Object();  A.__proto__ = B;

mGetter = function() {
       return this._m
};
mSetter = function (x) {
       check(this == _root.A);

B.m = 100;
C.addProperty("m", mGetter, mSetter);

check(C.hasOwnProperty('m'));
check(B.hasOwnProperty('m'));
check(! A.hasOwnProperty('m'));

A.m = 1;    //  trigger the setter,  got  4 checks in total.

d = A.m;
trace(d);   // expect 100 (B.m)
