+Be aware that this **does not work in Rails 7+**, as the lambda is evaluated
+immediately, and therefore requires your model to be already loaded.
+Workarounds include wrapping the initialization in `ActiveSupport::Reloader.to_prepare`, or creating a function that rescues unloaded constants with an initialization-time default, and running that in your lambda.
+
 In many cases this is not enough, so there are some other options to
 meet your needs.
