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
Or perhaps I misunderstood you?
