--- Comment #4 from js-gcc at webkeks dot org ---
Sure:

#import <ObjFW/ObjFW.h>

int
main()
{
        OFArray *array =3D [OFArray arrayWithObjects: @"a", @"b", nil];
        int someVar =3D 0;
        for (id object in array) {
                switch (someVar) {
                case 0:
                        OFLog(@"%@", object);
                        break;
                }
                OFLog(@"foo");
        }

        return 0;
}

Sorry, but something free-standing isn't possible as you need a collection
object. The same code should work with GNUstep by just replacing OF with NS=
