[IronPython] How to get a System.Exception inside a IronPython except: clause

[Dan Eloff]

Thanks Dino, That works.

Unfortunately FormatException() doesn't add the CLR stack trace, even
if it has been enabled in silverlight. If the exception is on the main
thread, and if it isn't thrown by the target of an invokation, and you
allow the exception to reach the top of the stack, you can see the CLR
stack trace. I guess for now, when I need to see the CLR stack trace,
the only way around that is to rearrange code so that those conditions
are met.

Is there anything that can (should?) be done about that?
