How about using a similar strategy to the current dict behaviour with __missing__ and defaultdict? Here's my suggestion:
- If a dict subclass defines __salt__, then it is called to salt the hash value before lookups. If __salt__ is undefined or None, the current behaviour remains unchanged.
This was my initial proposal, too. It took me a while to figure out that it won't work. Post-salting won't fix the issue. The random seed must be used as IV inside hashing algorithm. My brain was still in holiday mode and it took me a while to figure out the math. Sorry for any confusion! Christian
