The following code gives me compilation error. With const reference it's
ok. Is it right behaviour?

#include <boost/optional.hpp>
#include <boost/shared_ptr.hpp>

struct foo{
//    foo(int const& of) good
    foo(int& of) // error
    {}
};

int main(){
    boost::shared_ptr<int> ptr;

    boost::optional<foo> opt;
    opt = *ptr;
}
