I tried and it indeed made clang-format happy. However, gcc complained that
```
error: extra ';' after member function definition [-Werror,-Wextra-semi]
```

I tried various things and none of them can format it nicely (partially due to the fact that we are inside a macro definition).

Another thing we can do is to add 
```
// clang-format off
// define macro here
// clang-format on
```
