constexpr functions are crippled by the fact that they have to be valid at runtime. Things that are tantalizingly close but you can't quite do include returning a type that depends on the /value/ of a function parameter:
constexpr auto ptr_array(int N) -> int(*)[N]
{ ... }
If we would allow for constexpr functions that can only be evaluated at
compile time, we'd be able to do compile-time computation in a much less
template-heavy way.
Bristol 2013: Gregor thought that wrt general direction, constexpr is specifically not to have a constexpr-only model, and this issue would go into the opposite direction. NAD.
