How do you execute a generic body? Testable are generic instances.

You mean provable. Yes, in some cases it is possible to prove certain
properties which would hold for any instance of a generic body.

Right, but what you described is actually generic programming. Generic
programming = programming in terms of sets of types, rather than in terms
of individual types. I am not against it, I am against generic programming
done with generics, because done with classes (class is a set of types) it
is much safer and cleaner.
