I'm trying to write this prolog interpreter but i encountered a
problem. Let's say i'm evaluating a rule and i found a possible
solution. How will i store my current position in the parse tree of
the rule if i'm going back to it when i backtrack? I'm thinking of
using a stack but then, i have no idea how to use it for this
application. Do you guys have any opinions on the matter?
