Why does the first example `class A` work, but the second one

class B {
    immutable int[] b;

```

It implicitly converts `const` to `immutable`, but fails to do 
the same with an array. Is it intentional? Why?

Oh, is it because the first one is passed by value, but the 
second one is a reference?
