    Declaration of class variables or variables of a namespace are using =
this syntax.

    typedef int myint;

    namespace nnnn {
       extern int x;
    }

    myint ::nnnn::x =3D 0;

    Note that the problem only appears in case of userdefined type. =
Since than the syntax
    specifies, that a userdefined type can be specified using "::". For =
this reason we can not
    stop reading after "myint" and have to continue with "::nnnn". The =
parser does not know
    where to stop if a "::" follows.

    A second example is the use of class variables:

    class nnnn {
        static int x;
    };

    myint ::nnnn::x =3D 0;
The second example is more of an issue than the first one. Though, I =
doubt we'll stumble uppon it often. In most case we can rely on the fact =
that the static will be declared within the namespace and the type won't =
be prefixed:

namespace nnnn {
myint x =3D 0;
}

Or :

myint nnnn::x =3D 0;

Have you ever seen code as you pointed out ? I don't think I did.
