Surely it's more like taking shared_ptr and giving it an explicit get()
function? You can break invariants by doing stuff like:
but people are unlikely to do that by accident. Access to the underlying
raw pointer is essential for inter-operating with software which isn't
smart-pointer aware. So it is with OS handles.
