Using `decltype(auto)` as in `decltype(auto) NAME() -> int { return 42; }` will recognize the arrow as a trailing return type, but it doesn't really matter as its invalid syntax. I tried to find valid syntax where the arrow would be seen as a trailing return type, and I did with that second example

I'd just add a test to confirm that it works as expected.
