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.
This is true for any aggregate of builtins: struct S { char c; }; int i[5]; array is supposed to behave like an array. jon -- "Whenever you find that you are on the side of the majority, it is time to reform." - Mark Twain
