Hi,

This seems to break the following combination with overloaded -> operator - https://godbolt.org/z/jc6chKTdv

```
    template <class T>
    class Clone {
      public:
        Clone(const Clone<T>&);
        T* operator->() const;
        T* ptr_;
    };

    // Assume T* T::clone()
    template <class T>
    inline Clone<T>::Clone(const Clone<T>& t)
    : ptr_(t->clone()) {}

    template <class T>
    inline T* Clone<T>::operator->() const {
        return ptr_;
    }
```
