Thanks for your reply - definitely the second case - "variable
inheritance."

I looked at the implementation of inheritor and I wonder if you could
explain the reason for passing the ":+" symbol to the method. From the
implementation, you have this line:

    deflambda = lambda do
      define_method( key ) do
        defined?(super) ? super.__send__(op,obj) : obj.dup
      end
    ...

Why does the "+" method need to be called on the parent? I am hoping to
be able to understand what you are doing here so I can be a better
Rubyist!

Ara and Robert - sorry for replying directly to you. I meant to post to
the group but accidently clicked "reply to author". Thanks for your
responses also.
