hello dev,
I would like to ask dev whether the behavior is correct or not.

in cv.rb

class Greeding
  @@text = nil
  class << self
    def text=(word)
      @@text = word
    end
  end

  def text
    @@text
  end
end

Greeding.text= "hello world"
puts Greeding.new.text

result

bash-3.2$ ./mruby/bin/mruby ./cv.rb

bash-3.2$ ruby ./cv.rb
hello world

I expect Greeding#text return "hello world".
as follow code, it behaves the same way on MRI and mruby

class Greeding
  @@text = nil
    def self.text=(word)
      @@text = word
    end

  def text
    @@text
  end
end

Greeding.text= "hello world"
puts Greeding.new.text

FYI, mruby-1.1.0 work the some way as MRI. but mruby-1.2.0 does not.
