Detailed Description
template<typename _Tp, typename _Alloc = std::allocator<_Tp>>
class std::list< _Tp, _Alloc >"A standard container with linear time access to elements,
and fixed time insertion/deletion at any point in the sequence.
Template Parameters
_Tp Type of element.
_Alloc Allocator type, defaults to allocator<_Tp>.
Meets the requirements of a container, a reversible container, and a sequence, including
the optional sequence requirements with the exception of at and operator[].
This is a doubly linked list. Traversal up and down the list requires linear time, but
adding and removing elements (or 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 ( [] ) access is not allowed. For algorithms which only need
sequential access, this lack makes no difference.
Also unlike the other standard containers, std::list provides specialized algorithms
unique to linked lists, such as splicing, sorting, and in-place reversal.
A couple points on memory allocation for list<Tp>:
First, we never actually allocate a Tp, we allocate List_node<Tp>'s and trust [20.1.5]/4
to DTRT. This is to ensure that after elements from list<X,Alloc1> are spliced into
list<X,Alloc2>, destroying the memory of the second list is a valid operation, i.e.,
Alloc1 giveth and Alloc2 taketh away.
Second, a list conceptually represented as
A <---> B <---> C <---> D
is actually circular; a link exists between A and D. The list class holds (as its only
data member) a private list::iterator pointing to D, not to A! To get to the head of the
list, we start at the tail and move forward by one. When this member iterator's
next/previous pointers refer to itself, the list is empty.

(list< _Tp, _Alloc > &&) [default]
List move constructor. The newly-created list contains the exact contents of the moved
instance. The contents of the moved instance are a valid, but unspecified list.

(initializer_list< value_type > __l, const allocator_type & __a = allocator_type())
[inline]

template<typename _Tp , typename _Alloc = std::allocator<_Tp>> std::list< _Tp, _Alloc
>::~list () [default]
No explicit dtor needed as the _Base dtor takes care of things. The _Base dtor only erases
the elements, and note that if the elements themselves are pointers, the pointed-to memory
is not touched in any way. Managing the pointer is the user's responsibility.
