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?
