>             Project: Flink
>          Issue Type: Improvement
>          Components: Java API
>    Affects Versions: 0.7.0-incubating
>            Reporter: Chesnay Schepler
>            Assignee: Chesnay Schepler
>            Priority: Trivial
>
> The TypeExtractor currently doesn't check whether a KeySelector implements 
> the ResultTypeQueryable interface.
> Since i expected it to work i guess you can call ti a clarity issue. 
> Additionally, this change will allow me to use KeySelector for the Python API.
