I'm still can't work out the syntax for this.

To determine bounds of the array at compile time we can use the array as a
non-type template paramter:

const size_t size = array_size<myArray>::size;

However, I can't work out how to declare array_size as parameterized on
both N and T:

template< class T, size_t N >
struct array_size_holder

template< T[N] >
struct array_size
    enum result { size = N };


We can only call array_size if we know T and N in advance, which kind of
defeats the purpose <g> How can I deduce T/N without embedding array_size
into a wrapper template?
