Really?  I haven't tried the legacy interface in probably over a
year.  If you want to help bring that up to speed, I'd really
appreciate it.  Unless, of course, nobody is actually going to
use it. ;>

Right now, if you use the policy adaptor interface, you have
specify the MPL lambda argument for policies.  So you
would do this:

smart_ptr<my_type, array_storage<_> > p;

However, I will be adding metafunction classes which will
eliminate this step, allowing the same end-user syntax as
the template template interface:

smart_ptr<my_type, array_storage> p;

I just haven't had the time to put those in yet.  I would have
done it earlier, but I wrestled with the naming for a while.
