Reduced somewhat
Still requires the include though.

Reduced testcase without any includes or any magic functions:
```
template <typename> concept t = true;
template <typename> concept f = false;
template <int> struct TakeView {
template <typename T> class Iterator {};
template <f T> class Iterator<T> {};
template <t T> struct Iterator<T> {
friend auto operator+(const Iterator &it, int) {}
};
};
TakeView<1>::Iterator<float> tt;
```
