Yes, that's why I wanted to use enum.
Also because apparently Enums are the future and nobody uses object() any 
more :-)
Actually I don't really need all the features of Enums, I might just 
define my own class:
class Maybe:
 def __repr__(self):
 return "Maybe"
Maybe = Maybe()
I wish there was a simpler way to define symbols with identity but no 
state or behaviour...
