That's not a bad idea.  I tend to prefer self-documenting code whenever 
possible anyway, so if I a method ends that I don't intend to have a 
useful return value, I don't have a return statement with an argument, 
and if I intend a method that returns a useful value to return one that 
might be None, I do so expliclitly, rather than having the logic fall 
off the end of the function, making it unclear what was intended in the 
first place.
