Subject: [ruby-talk:23544] Fast reply needed: class var trouble

Ok its getting late over here in sweden and I'm tired. Can someone please
explain why this happens:

class T
  attr_accessor :t

  @@default_t = proc{|n| n.inspect}

  def initialize
    set_default
  end

  def set_default
    t = @@default_t
  end
end

t = T.new
p t.t         #=> nil

class T
  def set_default
    @t = @@default_t
  end
end

t2 = T.new
p t2.t        #=> #<Proc_0xa0389c0>

class T2
  @@t = 1
  def t
    @@t
  end
end

p T2.new.t  #=> 1

Why not a proc when t.t when it works as I'd expect in later cases?

Regards,

Robert
