Good point. It seems that after adding attributes to classes with instantiated objects, attribute access can only be done by attribute names with the current scheme. So if a class isn't marked final, attribute access is named only. > Maybe we should provide a version of C<getattribute> that takes relative > offset and the class name/PMC and then make that operation atomic? When the classoffset is relative the lookup is as expensive as with attribute names (I estimate - the cost of a hash lookup), that's the price of it. leo
