This suggestion is almost certainly wrong way to type this out. Just trying to show the idea. Does the .* here  capture `and`/`or` in the error message? If yes, match the possible valid cases with an or regex instead of allowing anything (another point for DAMP being more clear)

```suggestion
  // expected-error at -1 {{all arguments to}}{{and|or}}{{must have the same type}}

```
