williamr@4: /*
williamr@4:  * Standard C++ string class.  This class has performance
williamr@4:  * characteristics very much like vector<>, meaning, for example, that
williamr@4:  * it does not perform reference-count or copy-on-write, and that
williamr@4:  * concatenation of two strings is an O(N) operation.
williamr@4: 
williamr@4:  * There are three reasons why basic_string is not identical to
williamr@4:  * vector.
williamr@4:  * First, basic_string can always stores a null character
williamr@4:  * at the end (macro dependent); this makes it possible for c_str to
williamr@4:  * be a fast operation.
williamr@4:  * Second, the C++ standard requires basic_string to copy elements
williamr@4:  * using char_traits<>::assign, char_traits<>::copy, and
williamr@4:  * char_traits<>::move.  This means that all of vector<>'s low-level
williamr@4:  * operations must be rewritten.  Third, basic_string<> has a lot of
williamr@4:  * extra functions in its interface that are convenient but, strictly
williamr@4:  * speaking, redundant.
williamr@4: 
williamr@4:  * Additionally, the C++ standard imposes a major restriction: according
williamr@4:  * to the standard, the character type _CharT must be a POD type.  This
williamr@4:  * implementation weakens that restriction, and allows _CharT to be a
williamr@4:  * a user-defined non-POD type.  However, _CharT must still have a
williamr@4:  * default constructor.
