Still, I think it would be useful to expose the transform function. Any good reason not to? No good reason. What's the name? transformfunc?

There is one reason -- serialization. For example pickle saves the transform function as an argument for TransformDict constructor. Repr exposes the transform function too (in evaluable representation). Other serializers need the transform function too. My implementations expose it as public property (transform), your -- as private attribute (_transform).

Or perhaps I misunderstood you?
