Humor acknowledged, but...
Encapsulation can be syntactic sugar - and often is.
But the concept that it sugar coats is real enough.
You can write OOP by convention using lang
Well, I considered encapsulation as syntactical sugar.
And even prolog knows polymorphism, but I wouldn't call it OOP. (Yes, I
know in a typless context polymorphism doesn't mean too much. And btw,
if Python is a multi-paradigm language why doesn't support polygamy? :) )
Or maybe I'm wrong ...
I just found this message (because Mike posted the tinyurl)

Yep...across multiple lines.

So, in the following line
self.can.bind("",lambda x:self.handler(x,'release'))
the event-handler will call handler(event, 'release') when the
mousebutton is released, but the 'self' reference is automatically
passed over, so the result will be the handler(self,event, 'release') call.

If we're talking about data hiding, let me ask: why Python doesn't
implement data hiding (I mean 'private' and 'protected')? I consider it
a very important OOP feature, because that makes OOP different from
structural programming.

You're right, that I pressed reply instead of reply-to-all, so the list
didn't see my response. But this way you got my mail twice. Isn't that
annoying? Other maillist servers used to use the reply-to tag in the
message header.
