Y = ElementList = FSArray<X> would may look like ElementList inherits from FSArray and just binds the generic variable X. However, the FSArray<X> is actually a feature in ElementList. That is because it is not possible to inherit from FSArray. Cheers, -- Richard On 30.09.2013, at 09:35, Richard Eckart de Castilho <[email protected]> wrote: > That's an interesting question.
