Since I am heavily using Python 2.5 and RestrictedPython, I gave zope.proxy a
good shake. I also looked at the safe builtins declarations and updated them.
I have not yet reviewed the byte code hacks, which is the most complicated
aspect. How much experience do you have with the Python AST implementation?
You basically need to find out how the AST changed from Python 2.4 to 2.5 and
then make sure that every attribute and item access is overwritten with the
secure lookup version.
