Alternatively

namespace longish {
    namespace verbosish {
        namespace tediousish {
            struct X {};
            struct Y {};
            struct Z {};
        }
    }
}


int main() {
    namespace rly_shrt = longish::verbosish::tediousish;
    using rly_shrt::X;
    using rly_shrt::Y;
    using rly_shrt::Z;
    X x;
    Y y;
    Z z;
}
