C#(Mono) would say
int[]indices={0};
foreach(variinindices)
{
i=999;<-- Error CS1656: Cannot assign to 'i' because it is a 'foreach
iteration variable' (CS1656)
}

Digging a little deeper, I have some more confusion. This makes the

of:

public delegate void Thunk();
int main() {
Thunk thunk = () => {};
for (int i = 0; i < 1; i++) {

I believe foreach pass the values inside the array.
e.g.,
foreach (var i in indices) {
i = 999;
}
will not change indices[0] at all. A more strict language
will even forbid that "i = 999".
