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
Type "help", "copyright", "credits" or "license" for more information.
>>> 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
