How to embed with_scope in ActiveRecord class defnition?

Hi,

I want to limit the scope of records for a ActiveRecord class.

class Product < ActiveRecord::Base
end

I can use with_scope to limit the result set.
However, I want to limit it in the model in a fixed way so that
with_scope rule is implicitly forced.

For example,

class Product < ActiveRecord::Base
with_scope :find => {:conditions = “created_at > ‘2000-01-01’”}
end

How can I accomplish that?

Thanks in advance.

Sam
