Example from twitter: https://twitter.com/seanbax/status/1631689332007337985
which had discussion on similar bug.
```
template<int... Is> struct outer1_t {
void g() {
// Compiles for mysterious reasons.
int array[] { []<int... Is2>(){
int i = Is2;
return i;
}.template operator()<Is>() ... };
}
};
int main() {
// Compiles OKAY when this is commented out.
// ICEs when it's compiled.
outer1_t<1, 5, 10>().g();
}
```
clang issues a compiler error: https://godbolt.org/z/7f6E55svM
```
<source>:6:15: error: initializer contains unexpanded parameter pack 'Is2'
int i = Is2;
```
