I want to overwrite some of the accessor methods in my AC model to convert to/from Ruby types, but I can't, as AC defines the accessor methods at initialization-time, not at class-creation-time like with AR.

As a work around, I can overwrite them in my initialize(), but that's a bit hacky:

class Foo < ActiveCouch::Base

has :stuff

def initialize( *args )
  super
  def self.stuff
    @stuff ||= StuffType.new attributes[:stuff]
  end
end 

end

Ideally, I'd like to be able to pass a Ruby type to "has" and have AC do the casts and memoization.
