I saw it in a couple of places in Boost, in the "detail" namespace. I
think everybody would agree that Select is useful enough to be made a
first-class citizen, and this would be a good occasion to do that.
What header do you gusy think would be most appropriate?

That is a bug in Loki. According to the spec of the Ownership policy,
an implementation of that polisy must be a template of one argument.
So the correct setup is:
template <template <class> ThreadingModel>
class ref_count_mt : public ThreadingModel<ref_count_mt>
template <class P> class Impl
Now when someone wants to use a multithreaded reference counted
SmartPtr, they'd instantiate it with
A nit - you changed the com_ref_counted to call val->add_ref() and
val->release() instead of COM's consecrated val->AddRef() and
val->Release(). I guess things would work slightly better if you left
those two names unchanged :o).
Thanks again, Dave.
