[Issue 17512] Unclear error message when returning a reference to local variable

--- Comment #2 from johanengelen at weka.io ---
Or... it _is_ a frontend bug, as the compiler should deduce that the return
type cannot be 'ref'. It correctly deduces that ("does not return any
indirections") but because it added "return" function attribute earlier, the
error happens.

(sorry for the confusion, not thinking clearly)
