I might be missing something, but why is this a nice property? It seems
to open up the possibility of runtime errors and require that all result
types are default constructible. I don't think either of this, esp the
first point, is really that desirable.

As another point, is there a reason that pointers are restricted to raw
pointers? This restriction is not necessary -- see http://www.cuj.com/ex
perts/1811/henney_x.html which allows other smart object pointers.
