Subject: Re: Dynamic instances of a class.

OK, hate to multi-post, but wanted to let you know that i made it, is 
not really elegant, i wish there was a better way to do it, but at least 
i (kind of) get a solution for the main problem on this post.

Here is the code.

require 'csv'

class Motorcycle
  attr_reader :name, :weight
  @@count = 0

  def self.find (name)
    found = nil
    ObjectSpace.each_object(Motorcycle) { |o|
      found = o if o.name == name
    }
    return found
  end

  #Dynamically create instances of Motrocycle
  def self.create
  File.new('motorcycles.csv').readlines[1..-1].map{ |line|
    first, *rest = line.split(/,/)
    Motorcycle.new( first, rest )
    }
  end

  def initialize (name, weight)
  @name = name
  @weight = weight
  self.class.count += 1
  end

  def self.count
  return @@count
  end

  def self.count=( count )
  @@count = count
  end

  def available_colors
  end

  def has_abs?
  end
end

Is there any way to do it better, like, ¿ what is i didn't have 2 
columns but multiple columns?  (i was thinking of creating a array with 
the values and then using 2 for loops to retrieve each value, but that 
would have been really stupid i believe).
