I was only interested in it because it was easier for me to
understand template template parameters rather than the
class P1...P4 parameters with the mpl magic that's
used with them.  However, if nobody plans on using them
I'd rather not spend time on it.

So somehow this allows specifying parameters in any order, i.e.
I could specify the storage policy first and ownership last?
