Erh, not that way. Sorry.

You could have

class A
 @b = [1,2,3]
end

Which stores the array in a class-level instance variable.

This other one
class A
 @@b = [1,2,3]
end

stores the array in a class variable.

An instance variable would (or could, anyway) be used like this

class A
  def initialize
    @b = [1,2,3]
  end

  #accessor methods
  def b
    @b
  end
  def b= (value)
    @b = value
  end
end

Also, you can shorten the accessor methods to

class A
  attr_accessor :b
  def initialize
    @b = [1,2,3]
  end
end

Thank you for your brain.
