using cpp11::array;
// The make_array() function simply constructs an std::array.
// It is needed for cases where a std::array is used as a class data
// member and you want to initialize it in the member initializers list.
// It is also optimized: no spurious copies of the objects are made,
// provided the compiler does the NRVO. So this is better than
// default construction followed by assignment.
// I proposed it for Boost.Array, but it has not been integrated so far.
// See the thread starting at
// http://lists.boost.org/Archives/boost/2006/08/109003.php
//
// C++0x has it under discussion here :
// http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#851
// Hopefully C++0x will fix this properly with initializer_lists.
// So, it's temporary, therefore I do not document it and keep it internal.
// NOTE : The above is actually untrue ! It is possible to do :
// struct S2 {
// typedef boost::array<M,2> Ar;
// Ar m;
// S2 (const M&a) : m ((Ar) { { a, a } }) {}
// };
// without spurious copies... Except VC++ does not eat it :-(
// It's also untrue that this is not documented... It is !
