I used a modified version to return 0 when success:
[EMAIL PROTECTED] 30567]$ cat x.cc
template <typename T>
struct const_ref
{
const T* begin;
const_ref(const T* b) : begin(b) {}
};
template <typename T>
T sum(const_ref<T> const& a)
{
T result = 0;
for(unsigned i=0;i<1;i++) result += a.begin[i];
return result;
}
struct tiny_plain
{
int elems[2];
tiny_plain() { elems[0]=1; }
};
struct vec3 : tiny_plain {};
struct mat3
{
int type() const { return sum(const_ref<int>(vec3().elems)) == 1; }
};
int main() { return mat3().type() ? 0 :1; }
