> First, thanks for developing Spark. It's great.
> Maybe I'm trying to serialize weird objects (eg Shapeless constructs), but I tend to get quite a few NotSerializableExceptions. These are pretty annoying because they happen at runtime, lengthening my code/debug cycle. 
> I'd like it if Spark could introduce a serialization system that could statically check that serialization will succeed. One approach is to use typeclasses, perhaps using Spray-Json as inspiration. An added benefit of typeclasses is they can be used to serialize objects that were not originally intended to be serialized.
