+int **const * n_multiple_ptr();
+int *const & n_pointer_ref();
----------------
I'd like to see some more complex examples, like:
```
int const foo();
int const * const foo();

std::add_const<int> foo();

template <typename Ty>
std::add_const<Ty> foo();

auto foo() -> const int;
auto foo() -> int const;

template <typename Ty>
auto foo() -> std::add_const<Ty>;
```
I'm also very curious to hear how often this triggers on large code bases, especially ones that claim decent const-correctness.
