Github user tillrohrmann commented on the pull request: https://github.com/apache/flink/pull/1704#issuecomment-188320230 How do you want to do the implicit conversion if you return a `DataSet[T]`. If it makes the code more readable, then I think it's a good idea :-) We should have a test, which makes sure that the implicit conversion works when you import the corresponding package. That should be enough. I think we could add the documentation to the streaming guide. We could add a new page with the methods and link it from the scala tab of [DataStream Transformations](https://ci.apache.org/projects/flink/flink-docs-master/apis/streaming/index.html#datastream-transformations) in the streaming guide.
