Surely it's more direct, but I thought the original poster would like another
solution for its readablity. (I find the object.attr notation a bit more
readable than the dict[key] notation.) Probably it's a matter of taste.
Additionally, I tend to rarely use "low-level" data types because with classes it's
a bit easier to change the implementation later. I also tend to use objects with
rather "lean" interfaces; IMHO, a dictionary does too much here.
