I would hope to see close to the same semantics as std::array<T,0>,
which I believe allows data() to return nullptr.

Why the last char, rather than always having the size
(of whatever appropriate type) first? Is the idea that
this makes data() and c_str() essentially no-ops? I guess
the benefit of that depends on how often you need empty()
or size() vs. data() or c_str(). Or is there some other
