I am sure that works only because the static Integer.toString(int) and 
the virtual Integer.toString() return the same values. If you look at

Then for a X.&foo covering virtual and static methods, there is no way 
of knowing if we want to call the virtual foo or the static foo method. 
Both would take and instance of X as argument.
