It shouldn't do so on public method, as the problem is the exact 
same as override. It the method is private, then the problem goes 
away. Finally, if the method is protected, it doesn't make sense.

The information missing for the compiler at link time right now 
is the overridability of a method in a shared object. This can be 
solved for a lot of code by enforcing stringer semantic for 
extern.
