Subject: [ruby-talk:26252] adding instance variables to an existing class.

How might I add some instance variables to an existing class, such
as String, and have them initialized properly?

class String

    attr_accessor :pos

    alias old_initialize initialize
    def initialize(*args)
         old_initialize(args)
         @pos = 0;
    end
end

this = "Example"

didn't work.  In fact I got a warning to say it didn't work, which was
nice.  Does this suggest I'm nearly there? :-)
