Can someone test the following preprocessor code on the Sun and IBM
preprocessors:

#include <boost/preprocessor/detail/split.hpp>
#include <boost/preprocessor/punctuation/comma.hpp>
#include <boost/preprocessor/punctuation/paren.hpp>
#include <boost/preprocessor/tuple/eat.hpp>

#define IS_NULLARY(x) \
    BOOST_PP_SPLIT(1, IS_NULLARY_C x BOOST_PP_COMMA() 0) \
    /**/
#define IS_NULLARY_C() \
    ~, 1 BOOST_PP_RPAREN() \
    BOOST_PP_TUPLE_EAT(2) BOOST_PP_LPAREN() ~ \
    /**/

IS_NULLARY(())    // 1
IS_NULLARY(()abc) // 1
IS_NULLARY(+)     // 0
IS_NULLARY(xyz)   // 0

#define IS_UNARY(x) IS_NULLARY(IS_UNARY_C x)
#define IS_UNARY_C(a) ()

IS_UNARY((a))    // 1
IS_UNARY((a)abc) // 1
IS_UNARY(+)      // 0
IS_UNARY(xyz)    // 0

Regards and thanks,
