Quite the contrary, there is no List object, only pointers
to elements, so you never have a pointer to a List object.

By convention, many functions get and return the pointer to
the head, but other algorithms don't care where the list has
the head -- or whether it has any at all, you can make
a cyclic list of GList items, no problem (of course, you
must not use a GLib function that assumes a non-cyclic list).
