Issue Description:

Adding an async alternative to this method

func genericError<E>(completion: (String?, E?) -> Void) where E: Error { }

creates

func genericError<E>() async throws -> String where E: Error { }

which doesn’t compile because E is not used in the async method’s function signature.
