You should not define now as a macro. Not to mention that now is a very non-descriptive name. IMO, it should be spelled make_shifted_ptr<T>();
That is exactly the preferred way to wrap the constructor but I wanted to demonstrate it is perfectly and type-safe to use that macro as an alternative for this unique case. It does not limit in any way also the number of arguments and doesn't prevent usages of non-constant argument if the make_shifted_ptr<>() adds such modifier. The "now" keyword should be read as an interjection between the pointee and the pointer meaning: "the object pointed to by P is now a D". In the case the object created by "now" isn't affected to any pointer then the code isn't human-redable anymore. Ex.: shifted_ptr<int> P = now (int)(9); // Ok now (int)(10); // Apocryphal Nevertheless I will add the wrapper function but I haven't seen standard support for variable argument listing. -Phil
