There is another case that isn't being considered here. When doing real-time
programming, I consider implicit use of the heap a _bad thing_ because the
amout of time it takes to do the allocation is not deterministic. If I want
something to be allocated on the heap, I will say so explicitly. I do not
want a compiler that silently does something I didn't ask for.
