I'm creating a tagged array by inheriting from std::array, and I'm getting
warning missing-braces:

https://compiler-explorer.com/z/Eshjs8Eaz

```
#include <array>
#include <type_traits>

struct tagged_array: std::array<int, 4> { };

static_assert(std::is_aggregate_v<tagged_array>);

void foo() {
    [[maybe_unused]] tagged_array t{1,2,3,4};
}
```

GCC and MSVC are fine without any warning here.
