In the latest installment of Once, Weakly we'll discuss the use of
template metaprogramming to improve efficiency while keeping the users
of our facility in happy ignorance of what's going on behind the
scenes. Along the way we'll look at properly general generic
algorithms, automated loop unrolling, algorithm selection based on
whether arguments are integer constant-expressions, and the beneficial
aspects of ignorance.
