+1 on transform method on dicts.

What would transform do? Just canonicalize the key, or also save the original key? How much front-end work will each user have to do to actually use this new magic method to good effect?

Personally, if there's a bunch of push-back against just adding TransformDict directly, why don't we make it provisional? I thought that was what provisional was for (meaning: we're going to add it, PyPI is not really appropriate, there may be some API changes).
