C arrays aren't copy-constructable, true. But Boost.Array is,

struct
{
    T data[ N ];
}

is, std::tr1::array is:

"The conditions for an aggregate (8.5.1) shall be met. Class array relies on 
the implicitly-declared special member functions (12.1, 12.4, and 12.8) to 
conform to the container requirements table in 23.1."
