Comment(by anonymous):

 Also there is a problem with constness in charT.

 This causes problem:
 {{{
 #!cpp
 int main(int argc, char const* const argv[])
 {
   parse_command_line(argc, argv);
 }
 }}}

 1. parse_command_line cannot receive char const* const[[BR]]
 2. charT = char const , there is no specialization for
 basic_parsed_options<char const>
  So there is a need to remove_cv<charT> and only then specialize
 basic_parsed_options.
 [[BR]]

 {{{
 #!cpp
 template<class charT>
 basic_parsed_options<typename remove_cv<charT>::type>
 parse_command_line(int argc, charT* const argv[],
                    ....)

 }}}
