You don't use y as a list at all - you might as well inherit from object.  
And in that case you get a generic attribute container - as you said, like  
a dict but using attribute syntax (drawback: only valid names can be used  
as keys)
But I don't understand the "functie" usage - what's for? Perhaps if it  
used y.frequency - in that case a proper method would be better.
