 that you must write the `(())` in one sequence without intermediate whitespace
 so that rustdoc understands you want an implicit `Result`-returning function.
 
+As of version 1.37.0, this simplification also works with `Option`s, which can
+be handy to test e.g. iterators or checked arithmetic, for example:
+
+```ignore
+/// ```
+/// let _ = &[].iter().next()?;

+Note that the result must be a `Some(())` and this has to be written in one go.
+In this case disambiguating the result isn't required.
