There is a very simple and small adition to C, that would solve the generics problem, albeit without much typesafety and you'd probably need a bunch of macros to create really nice APIs: Marking function arguments as "inline" such that the argument must always be a constant expression and the compiler is supposed/forced to specialize the function. You can already write generic code that way currently, see qsort, but the performance is often very bad, because compilers don't specialize the functions aggresively enoigh. On the simple level, this would make thigs like qsort always specialize on the comparator and copy operation. But you can use this concept to create quite high level APIs, by passing arround constexpr type descriptor structs that contain functions and parameters operating on the types, somewhat similar to interfaces.
