I'm looking through cppreference.com here and I don't see a function
something like:

template< typename T, std::size_t len >
std::array<T,len> &pretend_is_std_array( T (&arg)[len] ); // returns
a reference

What are we supposed to do if we want to treat a C-style array as
though it's an std::array? Should we just reinterpret_cast?
