In Ruby, "this" is called self.

        length.times {|i| self[i] = "'" + self[i].to_s + "'"

A more idiomatic Ruby way to achieve the same thing would be use map or 
map!. The later method will replace each element of the array with the 
value produced in the block given.

   def quote
        map!{|element| "'#{element}'"}
   end
