Hi andreas

I digested a bit more my ideas and in fact having namespace to have 
shared variables is a big jump.
Too big may be. May be it would be interesting to see that more as 
module (I should read a bit ruby to see if I like what
they have).

Now I was really wondering what would be cost of removing Pool. I have 
the impression that
pool were introduced as an optimisation and are as such a static 
construct. What is your point of view?

I do not remember what you did about pool recently was it a step 
towards a possible extermination of POols :)
I like this metaphor.
