Ah, I see, so it's definitely needed. Hm. I think it's fine to have this issue
as a pointer. Is there any possible workaround one could imagine for this that
could be implemented in Spark? if not I am not sure what the action would be
here. It kind of sounds like SPARK-17368 could be a different manifestation of
the same problem anyway; it may not even be shell-specific?

You're absolutely correct, it is a Scala issue. I raised it here as well
though, since the -Yrepl-class-based option was originally created for Spark
(the standard object-wrapping behaviour had issues with the ClosureCleaner and
serialization IIRC) and was contributed back to Scala.
Should I close the issue?

I doesn't work in the Scala REPL, as SI-9910 indicates. But it is definitely
caused by -Yrepl-class-based, which the Spark shell sets. It seems like a Scala
issue then, but, I also don't know if -Yrepl-class-based must be set for Spark
or what it does. [~prashant_] you might know; is it possible this is just a
hold-over from old code we don't need? if we need it though, then this isn't
something Spark can fix unfortunately.

No, value classes work in the regular Scala REPL, just not spark-shell.

Is this not a Scala REPL issue then?
