What is it specifically your are looking for?
I'm basically looking for a way to initialize a Boost.Array. However, for me, the problem with this is larger, I want this class to be useful directly (without using another lib), safely (always initialized) and in the same way we use usual classes. I don't care about aggregates, as you can partially construct the object and officially only give compile time values. However I understand that some people like it and it is why I searched for a solution that let people use Boost.Array as an aggregate. But looking at old discussions, I pretty sure I'm not the only one who would like normal constructs for their arrays.
Maybe Boost.Assign can help you:
Ok, I was not aware that Boost.Assign works with Boost.Array sorry. This is good news and can help me thanks. However, I really prefer my solution. I think it is not to much invasive and it gives the user the usual construction syntax, which I think is something highly desirable. It gives an array concept closer to the STL container concept, by making array elements always initialized. And this without bugging too much those who wants to keep the Boost.Array as an aggregate. Also, it will gives compile time errors for things like that: array<int,4> a = list_of(1)(2)(3).to_array( a ); // compiles fine array<int,4, true> a(1,2,3); // doesn't compile array<int,4, true> a(1); // compile fine and repeats the value array<int,4, true> a(1,2,3,4); // compiles fine So, yes Boost.Assign can help, but no it is not what I was looking for ;-) -Vincent
