> The {{OptionTypeInfo}} does not have a proper {{equals}} and {{hashCode}} definition. As a consequence, types which contain an option type won't be detected to be equal even though the element type of the option is identical. 
> This can cause problems when you try to union two data sets of type {{DataSet[Option[Int]]}}, for example.
