In this specific case, I would prefer not to change the behavior. Whether lazy semantics in general is good or bad is difficult to say. In my personal experience, using lazy semantics in C++ often created more problems than it solved. Even the "caching" mechanisms that are sometimes really necessary often caused maintenance problems for me.
