...or you have a normal hash with one of the values as an array of the
keys in the order you want (I normally call it ":order"). Then when
you want to iterate you hash in order:
my_hash = {:name => "fred", :order => [:age, :foo, :name], :age =>
"21", :foo => "bar"}
my_hash[:order].each do |key|
puts my_hash[key]
end
Keeps it all "standard" and in one object... YMMV
