As usual, thank you Steven. Works great with raw and smart pointers now.

I initially thought about overloading ident_of for pointers and
references, assuming pointers were raw pointers and references were
smart pointers, but then I couldn't deduce the return type anymore (at
least not easily, I would have had to deduce the constness as well
just like in ObjectPtr, but via a meta-function this time I guess).
Forcing the deref at the call site is much cleaner and not much of a
burden. I'll try to remember than "traversing" a smart pointer chain
is much easier at the call site that way. --DD
