> Similar to https://issues.apache.org/jira/browse/FLINK-9221, it would be very
> handy to have a `Add method Writer[A]#contramap[B](f: B => A): Writer[B]`
> method, which would allow reuse of existing writers, with a "formatting"
> function placed infront of it. For example:
> val stringWriter = new StringWriter[String]()
> val intWriter: Writer[Int] = stringWriter.contraMap[Int](_.toString)
