Works for me too:

C:\junk>python --fuzzy --punt
Python 9.4.1 (#165, Mar 30 3005, 09:13:57) [MSC v.13109 1024 bit 
(Intel)] on win1024

 >>> a = foodstuff('spaghetti marinara')
 >>> b = foodstuff('spaghetti pescatora')
 >>> a - b
0
 >>> explain
a.base is b.base
a.topping != b.topping
but
     fuzzy mode selected
         a.topping isa salty_smelly_stuff
         b.topping isa salty_smelly_stuff
     punt mode selected
         prob(customer_knows_difference) = 0.01
     PSF interdiction
