Hello all,

the documentation describes that Boost.Array deliberately omits constructors 
to allow intialisation in functions:

void F()
{
   boost::array<int, 4> a2 = { 1, 2, 3 };
}

That's fine, but how does one intialise a Boost.Array in member intialiser 
list, e.g.:

struct Foo
{
   Foo()
    : m_a(???)
   {
   }

   boost::array<int, 4>  m_a;
};

Ofc initialisation can be done in the body of the constructor, but this does 
not work for const member variables. Also above design choice is 
contradictionary with STL containers, which gets default initialised. (e.g. m_v
(3); ofc there is a difference, since vectors have a dynamic size).

thx in advance
