/// A simple pure header implementation of VLA that aims to replace uses of
/// actual VLA, which can cause compile warning. This class by default creates a
/// stack buffer that can accomodate \p N elements. If the number of elements is
/// greater than \p N, then a heap buffer will be allocated and used to
/// accomodate the elements. Similar to the actual VLA, we don't check boundary
/// (for now), so we will not store the number of elements. We can always revise
/// it later.
