This would be true if Row[] was operator[](int&): an rvalue doesn't bind
to a non-const reference.
But if that operator is operator[](int) there is not problem: the
parameter, rvalue or lvalue, will be copied into the function in all cases.
Declaring a function like this:
void
f (const int);
makes no sense.
