Is the BasicObject class (from Ruby 1.9) planned to be
back-ported to
Ruby 1.8.x?

Also, will OpenStruct derive from BasicObject?  So that we
no longer
need to manually undef type and id to use those properties
in our open
structs?

  require 'ostruct'

  class OpenStruct
    undef type if respond_to? :type # deprecated in Ruby
1.8; removed
in 1.9
    undef id   if respond_to? :id   # same thing
  end

Thanks for your consideration.

I'M AFRAID IT IS A BIT TOO RADICAL TO CHANGE CLASS HIERARCHY
(OR
TOPOLOGY, RATHER) IN THE MIDDLE OF 1.8.  IT WOULD BREAK
CERTAIN KINDS
OF DEVELOPMENT TOOLS AND RUNTIME ENVIRONMENT (IDE/RAD
TOOLS,
SQUEAK-LIKE ENVIRONMENT, ETC.).

IT WOULD BE BETTER TO UNDEFINE METHODS WITH COMMON NAMES
INDIVIDUALLY.
LOSING OBJECT_ID, CLASS, DUP, FREEZE, TAINT, ETC. IS
OVERKILL I WOULD
THINK.
