It seems to me that a stack trace should always be attached to an exception object at creation time of the exception, and never at any other time. Sounds good in principle - but don't forget that normally the exception will be instantiated and then passed to the raise statement.

I've never seen a module level exception instance before. With the proposed changes, modules that do this would continue to work, surely ? So they lose nothing (compared to the current situation) by having the traceback information overwritten, they just can't take direct advantage of the new attribute.
