Yeah, geez. Single-rooted hierarchies of diverse functionality with a root class called "object" were discredited long ago, weren't they?
I am not suggesting a single-rooted heirarchy for *all* the classes as that would be stupid. MFC does it to support their own version of RTTI, memory leak tracking, etc. Java does it because it doesn't have templates. .NET has it because it treats every object as a COM object.
Python does it too. It's not neccessarily wrong for other languages; just C++.
hmm.... If C++ had implemented an 'Object' back in 1980, then "single rooted heirachy"s wouldn't be questioned... Mathew FWIW, the concept of 'flyweght' classes are great -> its a pity that other languages can't get true flyweight semantics.
