```
struct A {
template<typename T>
A(T& arg) {
static_assert(std::is_same_v<T, const char[1]>);
}
};
int main() {
std::initializer_list<A> { "" };
}
```
```
<source>: In instantiation of 'A::A(T&) [with T = const char* const]':
<source>:12:32: required from here
12 | std::initializer_list<A> { "" };
| ^
<source>:7:36: error: static assertion failed
7 | static_assert(std::is_same_v<T, const char[1]>);

• 'const char* const' is not the same as 'const char [1]'
