No. OOP and Generics are orthogonal in their goals: https://www.youtube.com/wa= tch?v=3D9lv2lBq6x4A The "tension" is due to a fundamental misunderstanding of what OOP *is*, wh= ich I think is due to the whole OOP-craze in academia, to the point where o= ther ideas were forgotten/discarded: https://www.youtube.com/watch?v=3D8pTE= mbeENF4&nohtml5=3D1 > I would say that modern C++ is like giving the template engine Turing com= pleteness with a syntax that is only slightly more readable than a Turing-m= achine's infinite-length tape and then making the entire reason for the lan= guage to exist to constantly put bandages on the never-quite-healing wounds= inflicted by the Turing-completeness-in-the-template-engine bull goring th= e rest of the C++ language with its horns, as if the rest of the language i= s a porcelain shop that stocks only red items. Oh wait. No =E2=80=9Clike= =E2=80=9D about it; that is what really happened. The amount of time/energy spent "fixing C" (and C++) is truly astounding. I wonder how well-off Ada would be if even 1/10th of that energy had been p= ut into addressing Ada's weaknesses, like (eg) few libraries, not as many t= ools, etc.
