No. dyn_array will not be resizable, and it is a a fantastic read safe strategy to check with a heap-allotted fixed-measurement array. Contrary to vector, it is meant to interchange array-new[]. Compared with the dynarray that's been proposed in the committee, this does not anticipate compiler/language magic to in some way allocate it about the stack when It's really a member of an item that is allotted over the stack; it just refers to a “dynamic” or heap-dependent array.
