Array of constant values as template parameter

[dude_1967]

Hello,

It's been a while since I checked in here.

Is it possible to use an array of constant values as a template parameter. I am writing preliminary benchmark code for ISO/IEC 14882:2011, so I could also use std::array or std::initializer_list.

In the mathematical template below, I use integer coefficients. The template has order 3.

template<const std::size_t order,
         const std::uint_least16_t B0,
         const std::uint_least16_t B1,
         const std::uint_least16_t B2,
         const std::uint_least16_t B3>
struct order3_math
{
  // Do order-3 math.
};

If I want to write more generic code, I could use order N and an array-type template parameter. But it does not work with compilers like VS2010 and GCC 4.6.x. Can it work or *should* something like this ever work without variadic templates?

// Can I do anything like this?
template<const std::size_t order,
         const std::array<std::uint_least16_t, order> coefficients>
struct orderN_math
{
  // Do order-N math.
};

Thank you.
Sincerely, Chris.
