Re: immutable ref foreach on values

[bearophile]

Dmitry Olshansky:

then every array is implicitly castable to tail immutable.
int[] array = [1, 2];

    foreach (ref immutable(int) x; array) {
        ...
        func(arr); // arr is mutable, thus func can change x
        // so x can be at most  const
    }

I understand, thank you :-)
