            Bug ID: 40380
           Summary: pack expansion not correctly expended with pointer
                    types
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++'17

The following code doesn't compile:

```
template<class ...Ts>
auto f3( Range r )
{
    auto apply = [&](auto* x){ return x->parse(r); };
    return std::tuple{apply((Ts*){})...};
}
```

The following error is returned:

```
<source>:22:37: error: pack expansion does not contain any unexpanded parameter
packs
    return std::tuple{apply((Ts*){})...};
                      ~~~~~~~~~~~~~~^
```
