Honestly, in my opinion, drop this. Don't make it more
'pointer-like'. Unless there's a good reason, or it makes sense
(Mathematical), then don't. You keep having half the tests using
regular &(address) operator; what's wrong with that?
Structs having no inheritance or virtual functions hold no extra
information, which is one reason you can void cast them from one
type or from void to their type without any issues. Casting to an
object though I am not sure, but I think it won't let you unless
it is able to. Besides once you have the pointer you don't really
need to deference unless you want to copy the struct.
I'm not sure how safe casting an object to void* would be, or
back. If you can't avoid it, I would say make overloaded methods
that do the intermediate work and make it transparent for you
afterwards.
