| Probably because it's converting some of those characters into a different character. There are things like trigraphs that when put into code are converted to different characters. I don't know if that's what is happening here, but it's possible. That /<>) code looks suspicious. |

| You haven't probably forward declared the function. Code: //uncomment to fix
/*
template <class T>
class X;
template <class T>
X<T> operator/(const T div, const X<T>& v);
*/
template <class T>
class X
{
friend X<T> operator/<>(const T div, const X<T>& v);
};
int main()
{
X<int> x;
10 / x;
}
//implementation
template <class T>
X<T> operator/(const T , const X<T>& ) { return X<T>(); }
