i don't know too much about prototype based coding - but are you saying this
is 'normal/correct/intended' behaviour?

   jib:~/eg/ruby/prototype/prototype-0.2.0 > cat b.rb

   require 'prototype'

   a = prototype{ x 42 }

   b = a.clone

   a.extend{ y 42 }

   b.x 42.0

   p a.x #=> 42
   p a.y #=> 42

   p b.x  #=> 42.0
   p b.y  #=> 42



   jib:~/eg/ruby/prototype/prototype-0.2.0 > ruby -Ilib b.rb
   42
   42
   42.0
   42


my understanding is that the above is generally accepted behaviour - but i'm
not sure.

cheers.
