[IronPython] Getting a call stack from an exception?

Could someone explain to this interested observer what is missing when the standard Python traceback functionality is used? Writing IronPython-specific code that isn't specifically involved in interacting with .Net seems against the "you can run the same Python code anywhere" notion that I expect to see.
Or did you mean "using the IronPython Engine" (aka "in pure C# code") when you said "in pure IP"? The sample code, after all, was Python and not calls to the IronPython Engine....

>Tracebacks are the correct way to do this, I recommend you install the standard Python library against IronPython to make this really useful then you can do import traceback and use its handy functions (otherwise youll be walking the traceback list in sys.exc_info() which wont be much fun).
