With this code:
```cpp
enum class E { a,b,c};
int main()
{
E e;
e = {1};
}
```
Clang 18,19,20 and trunk compile without error.
Narrowing conversion gives a error, but the diagnostic is not appropriate:
```cpp
long long ll = 0;
e = {ll}; // non-constant-_expression_ cannot be narrowed from type
// 'long long' to 'E' in initializer list [-Wc++11-narrowing]
```
Gcc:
```cpp
test.cpp: In function ‘int main()’:
test.cpp:6:9: error: cannot convert ‘<brace-enclosed initializer list>’ to ‘E’ in assignment
6 | e = {1};
| ^
```
