I would to generate this list with the preprocessot lib:

typename decay<T1>::type, typename decay<T2>::type ....

#define PARAM(z, n, data) \ typename decay< T ## n >::type

BOOST_PP_ENUM(n, PARAM, ~)

You can also use BOOST_PP_INTERCEPT, which was designed for this type of situation. #include #include BOOST_PP_ENUM_BINARY_PARAMS(3, typename decay::type BOOST_PP_INTERCEPT) The BOOST_PP_INTERCEPT macro is used to intercept and discard a numeric concatenation like BOOST_PP_ENUM_PARAMS does to its argument and BOOST_PP_ENUM_BINARY_PARAMS does to two arguments.
