`Result<(), ()>` This type is useful

Not only that. I'm mostly using it because it also enforces checking the result thanks to attribute on Result enum, while boolean can be accidentally ignored.

Sometimes it's really not worth it making a zero-size error type (because func is very specialized and there is only one thing that could go wrong), especially for internal helpers.

Generally I would be happy if this attribute would be just on boolean since almost every time you return a bool you actually mean Result<(), ()>.
