ObjectPtrT::operator-> const problem

I've noticed the const version of this method is returning a pointer to const.  The reason this is a problem is that it makes it impossible to log from const methods when LoggerPtr is a member variable:

class C
{
    public:
        C() : logger(log4cxx::Logger::getLogger("my logger")) { }

        void constMethod() const
        {
            // Error: can't do this because the const version of ObjectPtrT::operator->() 
            // must be used, and it returns a pointer to const T.
            LOG4CXX_DEBUG(logger, "debug message");
        }

    private:
        log4cxx::LoggerPtr logger;
};

In both versions of operator->, the ObjectPtrT itself cannot be modified, so it's not
clear why there is a need for a non-const version, or for a version
that returns a pointer to const.  It seems that in this case, the notion of pointer
constness is being conflated with the notion of pointee constness.

Surely the above example is not such an unreasonable a thing to expect to be able to do? :)

BTW, I wasn't sure whether this was more appropriate for the user list or the dev list (I'm subscribed to both).
