The classes will always focus on things like polymorphism and oh, isn't it great we can do *this* complicated language feature. IMHO, everyone should learn assembly first and C second. After that, its your choice, but at least you understand how your machine works. Of course, this is the view of a hardware guy <shrug>. anthony P.S. my favorite language is ML, but Zappa is in a mixture of C, C++, and assembly.
