std::sort() benefits a lot from being templated and not requiring callback
functions for comparing elements. (Many of the other operations are also
likely to benefit from directly seeing and handling the element type.)

I am curious to know if qsort() in the major standard library
implementations use the same algorithm as std::sort().
