+   *  Nathan Myers <ncm@cantrip.org>.
+   *
+   *  A string looks like this:
+   *
+   *  @code
+   *                                        [_Rep]
+   *                                        _M_length
+   *   [basic_string<char_type>]            _M_capacity
+   *   _M_dataplus                          _M_refcount
+   *   _M_p ---------------->               unnamed array of char_type
+   *  @endcode
+   *
+   *  Where the _M_p points to the first character in the string, and
+   *  you cast it to a pointer-to-_Rep and subtract 1 to get a
+   *  pointer to the header.
+   *
+   *  This approach has the enormous advantage that a string object
+   *  requires only one allocation.  All the ugliness is confined
+   *  within a single pair of inline functions, which each compile to
+   *  a single "add" instruction: _Rep::_M_data(), and
+   *  string::_M_rep(); and the allocation function which gets a
+   *  block of raw bytes and with room enough and constructs a _Rep
+   *  object at the front.
+   *
+   *  The reason you want _M_data pointing to the character array and
+   *  not the _Rep is so that the debugger can see the string
+   *  contents. (Probably we should add a non-inline member to get
+   *  the _Rep for the debugger to use, so users can check the actual
+   *  string length.)
+   *
+   *  Note that the _Rep object is a POD so that you can have a
+   *  static "empty string" _Rep object already "constructed" before
+   *  static constructors have run.  The reference-count encoding is
+   *  chosen so that a 0 indicates one reference, so you never try to
+   *  destroy the empty-string _Rep object.
+   *
+   *  All but the last paragraph is considered pretty conventional
+   *  for a C++ string implementation.
