=head2 Lists
Lists are defined over several element types, including
-C<isl_id>, C<isl_aff>, C<isl_pw_aff>, C<isl_constraint>,
+C<isl_val>, C<isl_id>, C<isl_aff>, C<isl_pw_aff>, C<isl_constraint>,
C<isl_basic_set>, C<isl_set>, C<isl_ast_expr> and C<isl_ast_node>.
Here we take lists of C<isl_set>s as an example.
Lists can be created, copied, modified and freed using the following functions.
int isl_set_list_foreach(__isl_keep isl_set_list *list,
int (*fn)(__isl_take isl_set *el, void *user),
void *user);

+ int (*fn)(__isl_take isl_set *el, void *user),
+ void *fn_user);
+
+The function C<isl_set_list_foreach_scc> calls C<fn> on each of the
+strongly connected components of the graph with as vertices the elements
+of C<list> and a directed edge from vertex C<b> to vertex C<a>
+iff C<follows(a, b)> returns C<1>. The callbacks C<follows> and C<fn>
+should return C<-1> on error.
