[boost] boost::optional<T&> assignment

Hi Fernando,

Why wouldn't this compile?

    int x = 1;
    optional<int&> a;
    optional<int&> b(x);
    a = b; // << *** Here *** <<

IMO, assignment should act like reference_wrapper:

    int x = 1;
    reference_wrapper<int&> a;
    reference_wrapper<int&> b(x);
    a = b; // OK

TIA,
