Current Psyco probably does not give a good estimate what
can be achieved. I've had very good and quite bad experiences,
yet. Psyco is going to start off from the ground, written in
Python, with the experience of its C alpha implementation.

I don't put any relevance into measurements, today,
and you shouldn't, either.
Some misbeliever muttered today, that Armin's brain has
shrunk from a planet down to an asteroid, by adopting this
PyPy project. Nice joke!

I positively did not reply, since I want us to prove him wrong.
This time, Armin's mission is not only a singleton planet, but
it carries impressingly intelligent life. And we will focus our 
collective work into creating an incredible outlet of imaginative
power.

(whow, did I say that? Can somebody please adjust tismer-bot?)

According to Stanislav Lem's immortal work, my current
project name proposal is

"Solaris".

If you want to avoid me telling that story in detail
on the sprint, be quick and read that book. !-)

all the best -- pirx

(yes, I do think he is caught in that time-loop trap)

(and he still thinks he can change the world. Together we can)
