+Subject: [PATCH] Edited scala checker to use scalac, with the
+ -Ystop-after:refchecks option.
+
+This means syntax checking is done via the compiler instead of the
+interpreter, so it won't choke on things like package definitions.
+
+The -Ystop-after:refchecks option will stop before code is actually
+generated, so we don't emit any class files.
