Lorenzo,
certo si, ci conosciamo!
beh... non e' che le "mie" idee siano particolarmente originali. 
C'e' un simpatico articolo del 1987 di Stein, Lieberman e Ungar (che mi
pare un vero genio) che si intitola "The Treaty of Orlando" che dice
testualmente:

"... the intent of object oriented programming is to provide a natural
and straightforward way to describe real-world concepts ...... 

... a fundamental part of the naturalness of expression provided by oop
is the ability to share data, code, and definitions .....

... many object oriented programming languages .. including Smalltalk
... have implemented this sharing through classes ......

... these mechanisms - class, subclass, and instance - impose a rigid
type hierarchy, needlessly restricting the flexibility of
object-oriented systems, and in particular do not easily permit dynamic
control over the patterns of sharing between objects...."

La mia nota era una semplice constatazione che la mia esperienza mi ha
confermato che queste idee sono assolutamente vere.... 

Ciao
Sandro
