When I call `length(s)` should I test for `s==nullptr` first? Should the implementation of `length()` test for `p==nullptr`?
int length(zstring p); // it is the caller's job to make sure p!=nullptr
int length(zstring p); // the implementor of length() must assume that p==nullptr is possible
int length(not_null<Zstring> p); // the implementor of length() must assume that p==nullptr is possible
int length(not_null<zstring> p); // it is the caller's job to make sure p!=nullptr
**Note**: `zstring` do not represent ownership.
