Subject Re: Spark on Scala 2.11

We can build the REPL separately for each version of Scala, or even give that package a different
name in Scala 2.11.

Scala 2.11’s REPL actually added two flags, -Yrepl-class-based and -Yrepl-outdir, that encompass
the two modifications we made to the REPL (using classes instead of objects to wrap each line,
and grabbing the files from some directory). So it might be possible to run it without modifications
using just a simple wrapper class around it. That would definitely simplify things!

BTW did the non-REPL parts run fine on 2.11?
