I don't agree, in some cases I use final class instances instead of heap-allocated structs even when I don't need polymorphic behaviour just to avoid pointer syntax (there is also a bit higher probability of destructors being called, compared to heap-allocated structs).
In some cases I've used a final class just to be able to use a this() with no arguments :-)
