Comment (by Amine):

 The attribute of the parser {{{ (qi::char_ >> qi::char_ >> qi::char_) }}}
 is {{{ boost::fusion::vector3<char, char, char> }}} so you should write
 your code this way :

 {{{
 #include <boost/spirit/include/qi.hpp>

 #include <cstdlib>
 #include <iostream>
 #include <string>

 int main(int argc, char * argv[]) {
     namespace qi = boost::spirit::qi;
     namespace fusion = boost::fusion;
     const std::string input("xabc");

     char x = 0;
     fusion::vector3<char, char, char> v;

     const int result = qi::parse(
         input.begin(),
         input.end(),
             qi::char_ >> (qi::lit("Z") | (qi::char_ >> qi::char_ >>
 qi::char_)),
             x, v
     );

     std::cout << (result ? "Success" : "Failure") << ": "
         << '"' << x << "\" \"" << fusion::at_c<0>(v) << "\" \""
                                << fusion::at_c<1>(v) << "\" \""
                                << fusion::at_c<2>(v) << '"' << std::endl;
     return result ? EXIT_SUCCESS : EXIT_FAILURE;
 }

 }}}
