If my object "A" inherits a getter or setter for property "a" from the 
prototype "B", assigning a value to this property does not really 
replace the inherited behaviour by a own property of object "A". The 
inherited getters and and setters on this property remain active.

This is an unexpected behaviour. Is this intented? How can I throw away 
such inherited setters and getters? I tried the delete operator, but 
this was useless. The inherited getter is still active.


js> function A(){}
js> function B(){this.__defineGetter__('a',function(){return false;})}
js> A.prototype=new B;
[object Object]
js> a=new A;
[object Object]
js> a.a=6;
5: TypeError: setting a property that has only a getter
js> delete a.a;
true
js> a.a=6;
7: TypeError: setting a property that has only a getter
js> a.a
false
js> 
 
                           js> a.hasOwnProperty('a');
true
