The warning ("discarding old <method>") comes up when you discard an
old method :-)

It basically means that you've overridden a method without saving
a path to the old version of the method.

For example:

  class String
    def split; end
  end

However, if you do this:

  class String
    alias :oldsplit :split
    def split; end
  end

the old method is still available (as oldsplit), so it has not
been discarded and there's no warning.
