 The following 2 samples are based on the solutions given, but
 still fail to compile.  I'm using g++ (GCC) 3.2.2 on i686
 
 #include <iostream>
 
 class BlackHole{};
 
 template <typename T> BlackHole& operator<<(BlackHole& bh, const
 T& dummy);
 template <typename T> BlackHole& operator<<(BlackHole& bh, T&
 (*dummy)(T&));
 
 int main() {
     BlackHole bh;
     bh << std::endl;
 }
 
 =======
 test.cpp: In function `int main()':
 test.cpp:11: no match for `BlackHole& << <unknown type>'
 operator

 #include <iostream>
 
 class BlackHole{};
 
 template <typename T> BlackHole& operator<<(BlackHole& bh, const
 T& dummy);
 (*dummy)(T&));
 BlackHole& operator<<(BlackHole& bh, int& (*dummy)(int&));
 
 int main() {
     BlackHole bh;
     bh << std::endl;
 }

 test.cpp: In function `int main()':

 operator
 test.cpp:7: candidates are: BlackHole& operator<<(BlackHole&,
 int&(*)(int&))
