You want #cattr_accessor
attr_accessor gives you:
def var; @var; end
def var=(val); @var = val; end
while cattr_accessor gives you:
def self.var; @@var; end
def self.var=(val); @@var = val; end
Which also means that you will normally do Polygon.sides.

attr_accessor writes out set/get for instance variables.
cattr_accessor writes out set/get for class variables.
Use those, and you don’t have to write out your own set/get

Hmm, as you are posting to the Rails mailing list, I assumed the Rails environment. You can include ActiveSupport for yourself to use these methods.
require ‘rubygems’
require ‘active_support’
