Added optional Occurs Check, suggested by Brad Lucier.
|
|
Brad also points out that the examples/houses.scm
|
|
puzzle, as written, needs the Occurs Check. ("as
|
|
written"...? Well, Prolog doesn't have the Occurs
|
|
Check, and this famous puzzle is offered as an exercise
|
|
in the Prolog textbook _The Art of Prolog_ (Sterling &
|
|
Shapiro). So I'm thinking perhaps there is a
|
|
less naive solution that doesn't rely on the Occurs
|
|
Check.)
