Let's talk about it when I will have succeded, to crow now I fear I will 
get
bad luck after me ;)

But, up to now, I it is going fantastic, complexity reduction compared 
to already
beautiful and powerful languages like Ruby ad Lisp, is astonishing. All 
the Classes are under my eyes.
I name them carefully and in 1 mouse click I am where i want to be !

The impression is, it takes me more time thinking of proper Class names 
and relations
than to write actual code.

. All data structures are inspectable ! Always. e.g-1. I can see the 
history of web calls, i store them
so i can spot where things went wrong. .e.g-2. I can watch inside my 
database anytime, it is
a child play, I don't need to memorize long queries and the less the 
output scanning the ugly flat string.

. I can change the program as it runs. Particularly, i can change what 
the server answers to
a particular call without shutting down the server. (to implement in the 
next days,
I just got how to do it) [I could do that in ComminLisp, but it is a 
while I don't use it]

. I plan to make the morph view of some structures, that will make 
checking them also better.
That in the future. If I enter Morphic now i will fail the deadline.

I am very enthusiastic, let' restart working !

Financial application are great for computing. I also made one in the 
past "bondinsider.it".
About bond portfolios. Unfortunately my associate who was in charge of 
sales was really unfit. The application
was built and never sold. I learnt a lesson. Non working associates must 
put a non trivial amount of money
in the company upfront so they are motivated to do their part of the 
work when
their time comes.

BTW. I know a guy who works in JP Morgan. He told me "Kapital" was to be 
abandoned.
A pity, it is one of the most popular sales pitch for Smalltalk. No idea 
what they are changing it with.

I go

Bye
