I still don't understand why not split Object into a set of 
interfaces like Printable, Hashable, Comparable and etc. The 
purpose of object itself is to have a common ancestor for all 
objects with a set of certain properties, and this can be easily 
fulfilled by an interface. Additional functionality is 
interpreted by a set of previously mentioned interfaces. Now 
since they are interfaces and no implementation can be there, we 
could provide user with a set of mixin templates that supply 
default behavior for implemented ones.

Those interfaces could also have pure/nothrow etc. subinterfaces 
that an object could implement.

Best regards,
Alexandru.
