       A string looks like this:

                                            [_Rep]
                                            _M_length
       [__rc_string_base<char_type>]        _M_capacity
       _M_dataplus                          _M_refcount
       _M_p ---------------->               unnamed array of char_type

       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_refdata(), and __rc_string_base::_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 emptystring _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.
