Hello @philnik777 
This change seems to have ( I think ) unintentionally changed the behavior of the following program.
Would you please check and fix if you agree with this analysis?

```#include <cstdint>
#include <type_traits>

template <int>
class class_type {
    int i;
};
typedef class_type<1> T;

static_assert(std::has_unique_object_representations<T[][2][3]>::value);
```
