So functions can be defined like this:
template
     ZEN_FUNCTION_REQUIRES(is_arithmetic<T>, is_arithmetic<U>)
     (T) max(T x, U y)
     {
         return x > y : x ? y;
     }
How is this different from:
template< class T, class U
         , BOOST_ENABLE_IF( and_< is_arithmetic< T >, is_arithmetic< U > > )
         >
T max( T x, U y ) { /**/ }
(T) here is passed to a macro name returned by ZEN_FUNCTION_REQUIRES.
This allows to generate normal enable_if code.
