Not saying your idea is false, but saying that always gets others riled up (and they are often in mayority of head count).

I think nowadays the single inheritance of Java, C# and vfp is a huge drawback, as "Mixin" leads to shorter/cleaner code.
As long as you don't go overboard (use it as all-purpose hammer), Multiple Inheritance / Mixin is good IMO.

C++ today is not something I really can comment on, as most of the enhancements since mid-90ies I never really tried.
If I have to I code basic C in the source fed to C++ compiler. At least some Linux inner circle coders feel similar, although with more experience to draw on ;-)
