But only when the function it self is inlined, which you quite often don't want. If you sort integers in a bunch of places, you don't really want qsort to be inlined all over the place, but rather that the compiler creates a single specialized copy of qsort just for integers. With something as simple as qsort compilers sometimes do the function specialization, but it's very brittle and you can't rely on it. If it's not specialized nor inlines then performamce is often horible. IMO an additional way to force the compiler to specialize a function based on constant arguments is needed. Something like spec
