What is the recommended way of initializing an array from a concatenation of other arrays?

list_of::range looks right and I would like to use something like:

array<int, 2> a = { 1, 2 }; array<int, 2> b = { 3, 4 }; array<int, 4> c = list_of<int>().range(a).range(b);

However, list_of<int>() inserts a default value (so that list_of<int>().range(a).range(b) == {0,1,2,3,4}).

Maybe we should add empty_list_of<int>() ? It's quite trivial to add. -Thorsten
