Yes, the library ought to contain something like that, as I have been
saying for years.  Probably it should be spelled something like:

     new_<shared_ptr<T> >(a, b, c, ...)

     new_<auto_ptr<T> >(a, b, c, ...)

Unfortunately, really making these functions work correctly for more
than about 5 or 6 arguments is currently not feasible because of
what's known as "the forwarding problem" (google it).

Boost Consulting is working on a project where we'll need this
functionality, so I hacked up the enclosed.  I'm going to generalize
it (and hopefully, optimize compilation speed) a bit and try to get it
into Boost.  In the meantime, enjoy.
