[20:30] <pilne> like, with lisp and scheme, it's hard to understand a lot withoutat
least a decent understanding how how things are put together with cons cells, but
with prolog it's terms and unification all the way down so far

[20:42] <White_Flame> well, prolog lists are cons cells and still have all the exact
issues with traversing, sharing, "dotted values" etc

Left recursion:
This arises when a rules causes the invocation of a goal that is essentially equivalent
to the original goal that caused the rule to be used.

This will recurse infinitely
person(adam).
person(X):-person(Y), mother(X,Y).
?-person(X).

This works (according to the book, either fails or something, but doesn't recurse infinitely)
