-# Extensions to +nil+ which allow for more helpful error messages for people who

-# NilClass#id exists in Ruby 1.8 (though it is deprecated). Since +id+ is a fundamental
-# method of Active Record models NilClass#id is redefined as well to raise a RuntimeError
-# and warn the user. She probably wanted a model database identifier and the 4
-# returned by the original method could result in obscure bugs.
-#
-# The flag <tt>config.whiny_nils</tt> determines whether this feature is enabled.
-# By default it is on in development and test modes, and it is off in production
-# mode.
