No.

#import <simtools.h> // initSwarm
#import <collections.h>
#import <objectbase/Swarm.h>

@interface Controller: Swarm
- (void)test;
@end

@implementation Controller
- (void)test
{
  id <List> l = [List create: globalZone];
  id <Index> index;

#if 0
  [l addLast: [SwarmObject create: self]];
  printf ("added: %p\n", [l getLast]);
#endif

  index = [l begin: self];
  while ([index next])
    printf ("%p\n", [index get]);
  [index drop];
}
@end

int
main (int argc, const char **argv)
{
  id controller;

  initSwarmBatch (argc, argv);

  controller = [Controller create: globalZone];
  [controller test];
  return 0;
}
