In the Wikipedia entry on Smalltalk, there is this line in
the history section, 3rd paragraph, added roughly a year
ago: "...Smalltalk-80 added [[metaclass]]es, to help
maintain the "everything is an object" (except private
instance variables) paradigm by associating properties and
behavior with individual classes, ..."<br>
<br>
<br>
Is this one of those esoteric details that mere mortals
are not meant to understand, or is this an error?<br>

<div>"(except private instance variables)" looks like a dig
or a jibe. I would have put it</div>

<div> "...Smalltalk-80 added [[metaclass]]es, to help
maintain the "everything is an object" paradigm by
allowing classes to have their own specific state and
behavior, ..."</div>
<div> </div>
<div>Perhaps they were trying to say that because Smalltalk
lacks private instance variables Smalltalk objects are not
true objects, which is I suppose arguable. But it makes
poor sense to state that private instance variables aren't
objects; public inst vars aren't objects either.</div>

<div>It's plain nonsense. Here's the edit that added the "private
instance" modifier:</div>

So now I just confused (more). Instance variables are NOT objects in
Squeak?<br>
