Generic algorithms won't 'get' it. In this light, it seems better to have a separate template for pointers, so you clients can specify what they want, explicitly: new_< T* > new_< auto_ptr<T> > new_< special_smartie<T> > (Seems tricky to deduce T but it might be doable).
Where operator() takes a variable number of arguments, forwarded to the constructor.
Isn't in-place construction the most general case?
It sure is, but not necessarily the most handy. How to tell e.g. std::transform to allocate memory for the transformed elements? Not sure I really got your point, here. Regards, Tobias
