Sean,

Hope that additional to the fun, we can converge to an understanding how can we 
increase Smalltalk popularity.

OTOH, I made the reference as a sample, I did not intend to have this as all 
encompassing list of issues nor start a thread about comparisons with other 
languages.

As I said earlier, what is 'trivial' or 'intuitive' for some is 'maverick' or 
'bizarre' for others, it is in the eyes of the beholder... ;-)
 
My main message is more around this: although Smalltalk was a very advanced 
technology when its inception, present status have almost all of its 
characteristics embedded in present technology.  Even, when newer concepts as 
xUnit have started in Smalltalk, the _concept_ was absorbed in mainstream 
technologies so again we're stuck with small delta between what Smalltalk does 
'better' than the incumbent technologies we would like to replace.

7 pages! (actually 6.5 - with embedded images)  That actually proves my
point vs. entire textbooks ;-)  Not to mention that:
* the first page and a half's examples are trivial and not exactly "traps"
(the fact that self is implicitly returned)
* the "10 + (10 negated) negated" "trap" executes intuitively and correctly
in Squeak
* the example of changing a loop while iterating with do: seems like C++
code translated literally into Smalltalk
* the last 1.5 pages are totally contrived (and use global variables which
are discouraged anyway; I haven't had to use one yet) - yes, if you *want*
to screw up the system, you can:
 #right 
 basicAt: 1 put: 119;
 basicAt: 2 put: 114;
 basicAt: 3 put: 111;
 basicAt: 4 put: 110;
 basicAt: 5 put: 103.
 #right
An equivalent argument is: if you hit your laptop repeatedly with a bat, it
will not work regardless of what programming language you were using, so you
might as well pick any

Well, that's just the point, isn't it?  We're talking about language
popularity and those are #2 and #3 on the TIOBE index.

I've been using Smalltalk for less than a year, but I'm already more
productive by far than in C, C++, or even Ruby, and haven't hit that limit
writing software for small businesses.  If there is a size at which the
benefit lessens, isn't it more likely caused by poor design/devs or any
number of factors (don't most large projects fail)?  It can't be the same or
worse to use a poor library in a dynamic live environment.  I recently wrote
a simple Ruby bridge and found it liberating to deal with the library in the
Smalltalk tools rather than in Ruby's code/run cycle.

I have never encountered this and I've often heard it said by dynamic
language experts to be mostly static language paranoia.  What is the
evidence that this becomes a severe problem in real-life dynamic systems?
