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.
