+/// An ilist node can be configured with compile-time options to change

+///
+/// By default, an \a ilist_node knows whether it is the list sentinel (an
+/// instance of \a ilist_sentinel) if and only if
+/// LLVM_ENABLE_ABI_BREAKING_CHECKS. The function \a isKnownSentinel() always
+/// returns \c false tracking is off. Sentinel tracking steals a bit from the
+/// "prev" link, which adds a mask operation when decrementing an iterator, but
+/// enables bug-finding assertions in \a ilist_iterator.
+///
+/// To turn sentinel tracking on all the time, pass in the

+/// isSentinel() function. The same option must be passed to the intrusive
+/// list. (ilist_sentinel_tracking<false> turns sentinel tracking off all the
+/// time.)
+///
+/// A type can inherit from ilist_node multiple times by passing in different
+/// \a ilist_tag options. This allows a single instance to be inserted into
+/// multiple lists simultaneously, where each list is given the same tag.

+/// remove(), which takes a reference to the node to remove, \a erase(), which
+/// takes an iterator or iterator range and returns the next one, and \a
+/// clear(), which empties out the container. All three are constant time
+/// operations. None of these deletes any nodes; in particular, if there is a
+/// single node in the list, then these have identical semantics:
+/// \li \c L.remove(L.front());
+/// \li \c L.erase(L.begin());
+/// \li \c L.clear();
+///
+/// As a convenience for callers, there are parallel APIs that take a \c
+/// Disposer (such as \c std::default_delete<T>): \a removeAndDispose(), \a
+/// eraseAndDispose(), and \a clearAndDispose(). These have different names
+/// because the extra semantic is otherwise non-obvious. They are equivalent
+/// to calling \a std::for_each() on the range to be discarded.
+///
+/// The currently available \p Options customize the nodes in the list. The
+/// same options must be specified in the \a ilist_node instantation for
+/// compatibility (although the order is irrelevant).
+/// \li Use \a ilist_tag to designate which ilist_node for a given \p T this
+/// list should use. This is useful if a type \p T is part of multiple,
+/// independent lists simultaneously.
+/// \li Use \a ilist_sentinel_tracking to always (or never) track whether a
+/// node is a sentinel. Specifying \c true enables the \a
+/// ilist_node::isSentinel() API. Unlike \a ilist_node::isKnownSentinel(),
+/// which is only appropriate for assertions, \a ilist_node::isSentinel() is
+/// appropriate for real logic.
+///
+/// Here are examples of \p Options usage:
+/// \li \c simple_ilist<T> gives the defaults. \li \c
+/// simple_ilist<T,ilist_sentinel_tracking<true>> enables the \a
+/// ilist_node::isSentinel() API.
+/// \li \c simple_ilist<T,ilist_tag<A>,ilist_sentinel_tracking<false>>
+/// specifies a tag of A and that tracking should be off (even when
+/// LLVM_ENABLE_ABI_BREAKING_CHECKS are enabled).
+/// \li \c simple_ilist<T,ilist_sentinel_tracking<false>,ilist_tag<A>> is
+/// equivalent to the last.
+///
+/// See \a is_valid_option for steps on adding a new option.
