unfortunately not:

try:
      #do stuff that throws exception in the CLR
    except:
      print Environment.StackTrace

gives what printed below, wich is fairly unusable.

   at System.Environment.GetStackTrace(Exception e)^M
   at System.Environment.GetStackTrace(Exception e)^M
   at System.Environment.get_StackTrace()^M

Boolean i
