outdated by the time this function returns and can therefore only be
used as an estimate.
.. c:function:: bool Z_member(const struct Z_head *, const itemtype *)
Determines whether some item is a member of the given container. The
item must either be valid on some container, or set to all zeroes.
On some containers, if no faster way to determine membership is possible,
this is simply ``item == Z_find(head, item)``.
Not currently available for atomic containers.

maybe flip the order of ``item`` & ``after``?
``Z_add_after(head, item, after)``
.. c:function:: bool Z_anywhere(const itemtype *)
Returns whether an item is a member of *any* container of this type.
The item must either be valid on some container, or set to all zeroes.
Guaranteed to be fast (pointer compare or similar.)
Not currently available for sorted and atomic containers. Might be added
for sorted containers at some point (when needed.)
