If in a D2 program I have an array of mutable items I may want to iterate on
them but not modify them, so I'd like the iteration variable to be const. This
is possible, but it seems I lose type inference:

void main() {
    int[3] array; // not const
    // foreach (const x; array) {}                // Error
    // foreach (const auto x; array) {}           // Error
    // foreach (const(int) x; array) {}           // OK
    foreach (const(typeof(array[0])) x; array) {} // OK

What's the correct syntax to use?
