QSP is as spiffy as a unique_ptr:

> std::unique_ptr with make_unique does not provide P1, P2, P5 and P4.

> P1 - safety: no access to the raw pointer
> P2 - safety: no accidental initialization errors or anything similar
> P3 - safety: no possible leaks
> P4 - convenience: forwarded constructor arguments (': d(1,2)' instead of ':
>    d(new Private(1,2))')
> P5 - convenience: default constructor works for no-arg Private constructor
>    (nothing instead of 'd(new Private())')
> P6 - convenience: no delete d;
> P7 - they are spiffy (Aaron)

As I said, this is for non-inherited privates.
