How?

You can't construct the base boost_array in the base class
initialization list of the constructor (because boost_array doesn't have
a constructor that takes arguments), and by the time you get into the
body of the my_array constructor it is too late - the boost_array is
already default constructed.

Having said which, personally I think that a seperate class with
constructors would be better than adding another template class to
boost::array.
