#This example demonstrates intersections.
#
#In order to buy rockets from Acme, you must be BOTH a preferred customer
#AND a WarnerBros character. In this example, the following query will be
#successful:
#
#    Acme.buy_rockets <-?- Coyote
#
#The following query will fail (because Batman does not have the
#attribute WarnerBros.character):
#
#    Acme.buy_rockets <-?- Batman
#
#Acme.buy_rockets <- Acme.preferred_customer & WarnerBros.character
#Acme.preferred_customer <- Coyote
#Acme.preferred_customer <- Batman
#WarnerBros.character <- Coyote
#
