What's the current status of this?

Sorry, I completely missed this earlier. Yes, something along those lines would be very useful.

I'm seeing the same issue as @lunaryorn and @alexeyr.

It appears that RC6 is having trouble with the `ImageSize` enumeration. I'm still investigating the root cause, but in the meantime I think that providing an explicit `Arbitrary` instance for...

OK, I think I see what's happening here, although I don't entirely understand why the behaviour has changed between RC4 and RC6. We can reproduce the problem with, ``` scala...

FWIW, I think the fix in ScalaCheck would be to move the implicit argument `a: Arbitrary[(T, U)]` after the argument `b: Buildable[(T,U),C[T,U]]` in the definition of `arbContainer2`. `b` won't resolve...

In fact, that might be a clue to a fix in scalacheck-shapeless ... the fix might be to duplicate `arbContainer2` in object `Shapeless` modified as described in my previous comment.

@InTheNow has verified locally that my suggested change in ScalaCheck does resolve the problem. So the change in scalacheck-shapeless should be good too.

No, I've not seen this before. It might be my fault, but I'm tempted to call this a compiler bug. Here's something else which works, ``` scala scala> type One...
