Static scope.

What's interesting for the current PF code graph implementation, is
that it is actually statically scoped.  All variables are bound at
compile time, which makes (data / code) hiding through local
definitions possible.

I'm not sure how to reflect this back into the language, but it could
be used to create local dictionaries, one of the things that was
really hard to do in original PF.
