Welcome to Scala version 2.10.0-20120604-160250-507be3e3dd.

scala> implicitly[ClassTag[List[T forSome {type T <: List[T]}]]]
<console>:8: error: exception during macro expansion: null
              implicitly[ClassTag[List[T forSome {type T <: List[T]}]]]
                        ^

scala> implicitly[ClassTag[List[Any]]]
res3: ClassTag[List[Any]] = ClassTag[class scala.collection.immutable.List]

I'd expect a valid ClassTag in both cases, not just the second.

Works fine with https://github.com/scalamacros/kepler/tree/nightly/2012-06-08.

I guess that's because I pretty much redesigned tag generation during the reflection refactoring.
