i don't thing that such pass in general worth the efforts. D programmers tend to use structures for local and short-lived objects. if i did `new`, chances are that i really want it on heap, and it will not be optimisable (i either returning pointer, or passing it to some function that stores it somewhere). so it can catch very rare cases for the cost of expensive interprocedural analysis. this makes some sense for C++, though.
