I think this is better placed on the std-discussion list[1], although I
doubt it will have effect.

If you want your code to be portable across different C++ versions I
would suggest using boost::unique_ptr[2] universally. If you just want
to delete objects when leaving scope, there is a more lightweight
alternative: boost::scoped_ptr and boost::scoped_array[3].
