Run javap and take a peak at them.  If I remember right, one is the
real code for the object, and the other is a bunch of static
forwarders which do two things: (1) hold the single instance of the
object, and (2) provide handy forwarders for access from Java.

Normally you'd either use it as an array (or one of its supertypes,
like Seq or Iterable), or you'd do toList.  If you are processing the
whole thing, anyway, then toList is as good as you can probably do.

If they are programming in Java, then the safest way to give them a
good API is to write the API using Java interfaces, and then implement
those interfaces in your Scala code.

If they are programming in Scala.... just ease them in, gently.  :)
