the problem occurs if i pass a primtive type into T. If i actually have
class X : boost::operators<X>
{
// ...
};
and than using X as a template parameter it works.
However it doesn't seem to accept primitive type because of the following
reasons...
error C2803: 'operator --' must have at least one formal parameter of class
type
