Both static non-templated member, templated function
can be a callback, but their combination cannot.
>How-To-Repeat:
class X {
	template< int N >
	static int foo( ) { return N; }
public:
	typedef int (*Function)( );
	Function bar( ) {
		return foo< 5 >;
	}
};

int main( ) {
	X x;
	x.bar( )( );
	return 0;
}
