[Newbies] I don't get it

Hi Erlis,


Class based language is very difficult for some people to grasp.  I've
trained a number of programmers.  There is this AH moment when people get
it.  Before that the idea is just so foreign to them that they have a
difficult time grasping what is going on.  I would often get the question,
"but where do I put the code".  The answer is everywhere.  Thinking in terms
of objects and programming their behavior makes sense.  People get that.
Make a Robot and teach it how to walk.  If I tell the robot to walk she
does.  Ok great.  Now I have all these objects that do stuff where do I put
the code?  This is where people stumble.  In my opinion the leap to
understanding is very short.  The answer is simple.  (Answer: It depends on
how you want to interact with the user).  


I do not believe that anything is screwed up.  It is just a conceptual model
that requires AH!


All the best,

Hi guys, 

I was reading recently Jim Coplien ideas about DCI and I was surprised with
the following statement: 

"The Smalltalk people, when they put together Smalltalk originally the
computational model was exactly right, in terms of thinking in terms of
objects. And then they screwed it up with the language. The language is so
class focused! Most languages that we're saddled with today had made this

you can find it here:

Does someone knows what Jim is criticizing? In which sense the computational
model was screwed by the language? I see smalltalk as a language that
express very well the intended computational model behind. 

But that's just me, maybe some of you could help me to understand Jim's
