Yet another std::vector issue...

Use-cases:
// Case 1
template<typename T>
using type = T;

// Case 2
struct Parent {
    template<typename T>
    using type = T;
};

// Case 3
template<typename T>
struct ParentT {
    template<typename DT>
    using type = DT;
};

struct Foo { int bar; };

void func()
{
    type<Foo> p1;
    Parent::type<Foo> p2;
    ParentT<Foo>::type<Foo> p3;
    // bar not highlighted
    p1.bar;
    p2.bar;
    p3.bar;
}
