update

I read all of it and this is semantically almost identical.

Larry just reused package for class ° and added more freedom:

• you can choose the name of your constructor(s) (usuall new)
• you can bless any reference as instance container not only hashes
• you won't have collisions between methods and instance vars
• class attributes don't collide with object attributes

Actually you can translate this whole tutorial almost 1-to-1 with a bit of syntactic sugar!

°) python doesn't seem to have anything like a package keyword
