--- Comment #2 from Daniel Stone <daniel at fooishbar.org> ---
The clue, however, is in the names of the parameters to the functions. For
instance, you do:
    struct wl_list list;
    struct {
        int something;
        struct wl_list link;
    } foo;

    wl_list_init(&list);
    wl_list_insert(&list, &foo->link);
    wl_list_remove(&foo->link);

At this point, foo has been removed from list (making its link member
dangling), but the overall list itself is still valid. Trying to remove a list
from itself does not make any real sense; instead, you remove an element from
that list.
