When parsing case classes with a List of Option[String], the option
classes get flatten out.
For case class Library(name:String, docs:List[Option[String]])
when I parse and extract it, i get:

Library(test,List(1, 2))

but I expect:

Library(test,List(Some(1), Some(2)))

The test unit is at https://gist.github.com/1077437
Is this the expected behavior or a bug in lift-json 2.4M1?

Joni Freeman states: " extracted type must be the same type as given to the extract function"
