Aggregate initialization is an important part of the array concept, allowing it to act largely as a plug-in replacement for language arrays, with the bonus it can be passed by value as well as by reference. The main drawback here is that we cannot deduce the size of a boost::array, as you can with a language array.
From my point of view, the main drawback is that in the following code: vector<double> v1(6); array<double, 6> v2; v1's content is initialized, v2's content is not. In fact, array is about the only class I know of that as a default constructor that does not initialize member data to a legal and documented value. This I strongly dislike. By the way, I also dislike the fact that double d; does not initialize d, but at least people know that fundamental type do not behave well when initialization is concerned. -- Loïc
