 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()?;
-///# Some(())
-/// ```
-```
-
-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.
