While playing around with boost::optionals I had code like the following

struct A { ... int i; ... };

boost::optional a; // do something with 'a'

// optional-projection to a::i boost::optional<int> a_i; if(a) a_i = a->i;

Could you give us an example here that would compile?

Ok, you meant boost::optional<A> a; Now I see what you are talking about. Regards, &rzej
