+When used with Rails 2.3.*, Comma also adds support for exporting named scopes:
 
+    class Book < ActiveRecord::Base
+      named_scope :recent,
+                  lambda { { :conditions => ['created_at > ?', 1.month.ago] } }
+
+      # ...
+    end
+
+Calling the to_comma method on the named scope will internally use Rails' find_each method, instantiating only 1,000 ActiveRecord objects at a time:
+
+    Book.recent.to_comma
