Edge case where you cannot modify mutable pointer

[Hejsil]

const S = struct {
    a: u8,
};

test "" {
    const s = &S{ .a = 2 };
    @compileLog(@typeOf(s));
    s.a = 2;
}

| *S
/home/hejsil/repo/zen/test.zen:7:5: error: found compile log statement
    @compileLog(@typeOf(s));
    ^
/home/hejsil/repo/zen/test.zen:8:9: error: cannot assign to constant
    s.a = 2;

As we can see from the error, the @compileLog prints that s is a mutable pointer, yet, you cannot modify it's memory. Change s to be a var instead of const makes this compile.

adding that this works

const S = struct { a: u8 };

test "" {
    var r = S{ .a = 2 };
    const s = &r;
    s.a = 3;
}
