Hey, it's only *one* new keyword yet. :)

Admitted, local blocks are more Adaish, but with this approach, I was 
trying to avoid introducing a lot more keywords. There still probably 
will be some, because there are more constructs like "barrier", 
"workshare" (which I didn't fully understand yet) and "section".

And well, such blocks are already known in Object Pascal. Just look at 
them as in object declarations the public/protected/private modifiers.

Yes. I agree with that. The problem is that there are more "variable" 
types than just shared and private (like "firstprivate"), so it might 
prove to be quite difficult to do that if you only have local 
functions. I just didn't come to that part yet.

I'll probably update the WiKi this evening/night (can't do that from 
work, where freepascal.org still times out).
