There should definitely be frozendicts and I've been wanting to write an implementation. The main thing about them is if they are implemented as tree structures instead of hashes, you can efficiently make differing versions of them that share structure, basically giving you version rollback for free. And since they are immutable, you can share them between threads without needing to mess with locks. I've posted about this a couple times in the past. -- http://mail.python.org/mailman/listinfo/python-list
