Well, I started using it in policy_ptr, where basically all the functions
*are* very short and inlined, where performance matters, and where
the library doesn't know what types are going to be passed to it. I
think in the vast majority of cases, it won't make a difference,
because a fundamental pointer type will be used; but I like to
think that I'm improving the QoI by using it anyway.
