hi Shehio,

  so, a couple of things...

> # whats wrong with that
> class Whatever
>   attr_accessor :array
>   @array   ### THIS IS NOT NECESSARY
>   def initialize
>     @array = []  ### THIS IS NOT NECESSARY EITHER
>     @array = ["apple", "banana", "peach"]
>   end
    ### THE FOLLOWING IS NOT NECESSARY
>   def array []= (i,value) # setter
>     @array[i] = value
>   end
>   def array[] (i) #getter
>     @array[i]
>   end
> end


  this code could read:

    class Whatever

      attr_accessor :array

      def initialize
        @array = ["apple", "banana", "peach"]
      end

    end


  and all of this will work just fine:

shehio = Whatever.new
puts shehio.inspect
puts shehio.array
puts shehio.array[0]
puts shehio.array[1]
puts shehio.array[2]
shehio.array[0] = 1
shehio.array[0] = 2
shehio.array[0] = 3
puts shehio.array[0]
puts shehio.array[1]
puts shehio.array[2]
