[AccessD] Class costs & benefits

Hi Arthur,

Have a look - Ruby has multiple inheritance features implememted using so called Mix-ins to effectively solve the issue you mentioned:

I'd bet C# and VB.NEt will follow this pattern or something like that in the future versions (but not yet in next versions C#4.0 and VB10 (VBx))...

Thank you.
