What I forgot to mention is that if you do:
module AccountSystem
class << self
attr_accessor :account_system_type
end
end
You are actually putting the attr_accessor on the class Module, not on
the class that AccountSystem will be included in. You need to use the
included method, or use the extend method and refactor your module a
bit.
