Not sure if this is a bug or not, bug gcc compiles this code just fine:
```
template<typename Base>
struct Mixin {
static constexpr Base base{};
};
struct A {
Mixin<A> m;
};
```
while clang argues:
```
<source>:3:25: error: constexpr variable cannot have non-literal type 'const A'
3 | static constexpr Base base{};
| ^
<source>:7:14: note: in instantiation of template class 'Mixin<A>' requested here
7 | Mixin<A> m;
| ^
<source>:3:25: note: incomplete type 'const A' is not a literal type
3 | static constexpr Base base{};
| ^
<source>:6:8: note: definition of 'A' is not complete until the closing '}'
6 | struct A {
| ^
