Well, that would leave us needing a new word for what used to be
"yield" :-)  I don't think that values in CL does what yield does, does
it?  Wouldn't this (returning multiple values) be closer?

  def thing
    return 1,2,3
  end

In any case, yield and related iterator behavior are very central to
Ruby; I doubt they're in flux or under consideration for elimination.
At least, I hope not :-)
