Description Markus Schorn CLA 2011-04-04 04:53:00 EDT 
There is an ambiguity between template-ids and binary expressions. The parser handles it via a heuristics. The following example is extracted from the gcc-header files:

template<bool> struct S {
	static int m();
};
int f();
int s;

void test() {
    S<1 && 2>::m();        // m is member of S
    s<1 && 2>::f();        // f is global
}
