Hello! I have one more need about tuples. I need two functions: one for general case and one for tuples returned by make_tuple function. It is equal to the following functionality provided by boost::variant library:
"// general cases template <typename T> void some_func(const T &); template <typename T> class some_class;
// function template overload template <BOOST_VARIANT_ENUM_PARAMS(typename T)> void some_func(const boost::variant<BOOST_VARIANT_ENUM_PARAMS(T)> &);
// explicit partial specialization template <BOOST_VARIANT_ENUM_PARAMS(typename T)> class some_class< boost::variant<BOOST_VARIANT_ENUM_PARAMS(T)> >;"
For fusion, you can use enable_if and fusion::is_sequence. HTH. Cheers, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
