This is like saying verb is a word not grammar. Obviously, you are on a
crusade without having any reason for it, so you either have to bluff
your way or are blissfully unaware what you are mussing. Try fixing my
code snippet in which I demonstrated the inconsistency when mixing
Struct and class. Get the following to run, without annulling the Struct
with {{ attr_accessor :num }}:

  S = Struct.new(:num)
  class S
    def initialize n
      super
      self.num = n + 5
    end
    def num=(n); self.num = n + 5; end
  end

  s = S.new(10).num # => ./teststruct.rb:9: \
               stack level too deep (SystemStackError)
  p s.num #=>
  s.num = 1
  p s.num #=>

Am I really blowing this out of proportion? I'm just stating the 
obvious. This stuff is broken if used for more serious work than playing 
with simplistic examples on some forum.
