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...
