That's looks easy, except it won't work in Silverlight. You can only
access public members in Silverlight, even via reflection. Do I have
any options in Silverlight?
Why on *earth* does Jinja need to do that? It's truly horrible. Python
is a dynamic enough language that there are hundreds of way achieving
even the strangest of behaviour without resorting to stupidity like
that. Bug them to change it...

I'd imagine Cecil would work but it might be overkill - you could just use .NET
reflection:
try:
raise Exception()
except:
import sys
tb = sys.exc_info()[2]
tbtype = type(tb)
import clr
import System
clr.GetClrType(tbtype).GetField('_next',
System.Reflection.BindingFlags.NonPublic|System.Reflection.BindingFlags.Instance).SetValue(tb,
None)
Just replace None w/ the value you want to set it to. For 1.x change '_next'
to 'next'.

Could you use something like Cecil for this?

It's readonly in Python, and that's the way it's meant to be. But I'm
porting Jinja2 to IronPython (Silverlight hopefully) and Jinja uses
ctypes to dig deep into CPython's guts and make a function for setting
tb_next on traceback objects. Playing by the same dirty, no holds
barred rules, is there a way to set tb_next on traceback objects in
IronPython?
