I can see the usefullness in this, thanks for the heads-up - but I
can see that if I had a lot of attributes, it would seem somewhat
awkward:

class Thing < Struct.new (:attr1, :attr2, :attr3, :attr4, :attr5, 
                                           :attr6,:attr7, :attr8, :attr9, :attr10 )
  # do stuff
end

Besides, I just get a weird feeling that this Struct approac is kinda 
odd - to tricky or something - as I'm learning ruby, I'm trying to stick 
with  the most common idioms and oop practices.

I guess it's just a matter of personal aesthetics? :

class Thing
  attr_accessor :attr1, :attr2, :attr3, :attr4, :attr5, 
                          :attr6,:attr7, :attr8, :attr9, :attr10
  # do stuff
end


Thanks,

Corey
