This:
```cpp
#include <optional>
using T = std::optional<int>;
int main() {
auto foo = []() -> T {
return T{1};
}().value();
}
```
gets formatted to:
```cpp
#include <optional>
using T = std::optional<int>;
int main() {
auto foo = []() -> T {
return T{1};
}()
.value();
}
```
Which seems like a bug (why is the `.value()` part there?).
On the other hand this (note: trailing return type omitted):
```cpp
#include <optional>
using T = std::optional<int>;
int main() {
auto foo = []() {
return T{1};
}().value();
}
```
gets formatted to:
```cpp
#include <optional>
using T = std::optional<int>;
int main() {
auto foo =
[]() {
return T{1};
}()
.value();
}
```
which is much more reasonable.
