This requires further explanations. Since generics are themselves static,
the problem is not in types being static, but in something else.

Actually, the question is whether a static type system should be extended
by means of generics or by other means. I saw no discussion why this should
be done with generics, as well as any discussion about the power and
desired properties of a static type system.

To me it is obvious that a type system serves reuse. The property of being
static is aimed at correctness checks/proofs. In this context generics look
quite disappointing.
