I think there will almost certianly be a compiler error if somepone tries to pass an array pointer, since the dereferencing operations are not supported.

Seriously? Why not?

Because it's more fun to implement that way :-)

It seems as though dereferencing should be fine. And incidentally, upcasting should be fine, too:

S_ptr<D[]> -> S_ptr<B>

;-)

Seriously, maybe this is an indictment of the concept of smart pointers to arrays. It's nice to say we want smart pointers to arrays to behave like ordinary arrays -- but ordinary arrays are really wierd! ;-) Jonathan
