+   *
+   *  Meets the requirements of a <a href="tables.html#65">container</a>, a

+   *  %exception of @c at and @c operator[].
+   *
+   *  This is a @e singly @e linked %list.  Traversal up the
+   *  %list requires linear time, but adding and removing elements (or
+   *  @e nodes) is done in constant time, regardless of where the
+   *  change takes place.  Unlike std::vector and std::deque,
+   *  random-access iterators are not provided, so subscripting ( @c
+   *  [] ) access is not allowed.  For algorithms which only need
+   *  sequential access, this lack makes no difference.
+   *
+   *  Also unlike the other standard containers, std::forward_list provides
+   *  specialized algorithms %unique to linked lists, such as
+   *  splicing, sorting, and in-place reversal.
+   *
+   *  A couple points on memory allocation for forward_list<Tp>:
+   *
+   *  First, we never actually allocate a Tp, we allocate
+   *  Fwd_list_node<Tp>'s and trust [20.1.5]/4 to DTRT.  This is to ensure
+   *  that after elements from %forward_list<X,Alloc1> are spliced into
+   *  %forward_list<X,Alloc2>, destroying the memory of the second %list is a
+   *  valid operation, i.e., Alloc1 giveth and Alloc2 taketh away.
