Hmm have ever used PIL.

Lots of returns are tuples (admittedly not variable length)

things like size are an example. (100,200) or

w,h = object.size()    #  Actually it might be a property but really I 

                        #don't see a big difference.

IMHO this doesn't warrant being wrapped in a class.

and is much better than

h = object.height()
w = object.width()
