Is it time to wrap operator new()? For example:
boost::shared_ptr<Widget> wp2 = boost::make<Widget>(a, b);
with something like:
template <typename R, typename A, typename B> inline raw_ptr_t<R> make( A &a, B &b ) { return raw_ptr_t<R>( new R( a, b ) ); }
Users being allowed to specialise make<> with their own factory code if desired.
At first glance and except for: 1) terseness 2) limitation to 2 arguments 3) the need for separate allocation for the overhead I can't see much difference between the above make<R,A,B> and auto_overhead at: http://cvs.sourceforge.net/viewcvs.py/boost-sandbox/boost-sandbox/boost/managed_ptr/auto_overhead.hpp?rev=1.2&view=auto AFAICT, it would be a simple change to just skip the overhead allocation by making the overhead in auto_overhead an empty base class.
