Why does Prolog match (X, Xs) with a tuple containing more elements? An example:
test2((X, Xs)) :- write(X), nl, test2(Xs).
test2((X)) :- write(X), nl.
test :-
read(W),
test2(W).
?- test.
|: a, b(c), d(e(f)), g.
a
b(c)
d(e(f))
g
yes
Actually this is what I want to achieve but it seems suspicious. Is there any other way to treat a conjunction of terms as a list in Prolog?
