[Twisted-Python] fwd: Re: [Python-Dev] Zope porting to jython

Other then the interesting thread, note the description of
the way Zope does "safe python".
Glyph, should I start adding Depends: python-bytecodehacks? ;-)

Zope doesn't use restricted execution.  In Zope 2.4, the
RestrictedPython project uses the compiler package to generate safe
bytecode from Python source code.  I presume something similar could
be achieved using jythonc, but don't know how hard that would be.

I don't think there's an official PythonLabs opinion on this in
general.  If we have one its this:

The project(s) -- including the just announced phabric
effort -- are worthwhile.  We are happy to give advice and make
changes to help the projects where we can.  I expect the same holds
true for the rest of Zope Corp.

If there are genuine CPython/Jython incompatibilities that hinder the
project, there's no reason not to fix them.  The project may also
serve as a vehicle to further explore what metaobject protocols should
be exported by Jython.
