Anybody who is interested in looking at what Alan Kay and Smalltalk are 
doing try out Squeak.


There are several parallels between Squeak and Erlang. Each have their 
pros and cons. Squeak is a much better understanding of true OO than you 
will have found other places. That said, Squeak is looking for better 
ways to implement solutions. OO is one way, however the Squeak community 
is very open minded to other ways of expressing solutions. They are open 
to learning what other language communities have learned.

While Squeak may not ever become a 'Functional' language you may find it 
interesting. There was a recent discussion on modeling things in a more 
'declarative' manner. So with Squeak (not necessarily other Smalltalks) 
there is an openness for better solutions.

Interestingly enough in regarding this thread, Squeak already does it's 
own GUI. It does not use native widgets. Squeak is very cross-platform 
to about 30-40 (I think) platforms currently.

It is open source and ready to play.

An OS is being written in Squeak called OpenCroquet.

Squeak currently isn't as proficient for massive parallel/concurrent 
applications as Erlang. But there is a desire to get there.

Squeak is very much a living environment. It is very malleable and able 
to be changed while being used. Like the 'Hot Code Replacement' thread 
in comp.lang.functional. It's meant to staying running indefinitely.

Not trying to hijack the Erlang list here. Just wanted to inform those 
who may be interested.
