If you convert your Rails 2.1 app to Rails 2.2RC2, you’ll see this  
fancy error message as soon as you start script server:

* * *

## ArgumentError “Anonymous modules have no name to be referenced by”

Stack trace will lead you to dependencies.rb:572

Solution:  
Rename your application.rb to application\_controller.rb

All will be well after that. Though a friendlier error message would  
be very nice. I imagine a majority of Rails developers will run into  
this problem.

Hope this helps…

This SHOULD not happen for 2.2 RC2 because 2.2 already has a separate  
branch. And renaming application.rb → application\_controller.rb is an  
edge only change.

Ah, ok. My bad. I grabbed trunk instead of RC2
