Depends on how you want to use that functionality. In my use case I only 
need to catch the excpetion once.

Note that in your code the exception has not the right type which is 
what I targeted in my last posting. I.e. the following will raise an 
Exception if function is decorated:

try:
     print funktion()
except ArithmeticError:
     pass
