Re: [boost] [POSSIBLE BUG] boost::fusion::fold des not work as advertised

The test now is:

struct make_string { template<typename T, typename State> struct result { typedef std::string result_type; };

template<typename T> std::string operator()(const T& t, const std::string& str) const { return str + boost::lexical_cast<std::string>(t); } };

That's not what I meant. Don't just substitute the nested typedef but the whole metafunction: struct make_string { typedef std::string result_type; ... Regards, Tobias
