Destructuring with private and protected members

[xLama]

class Foo {

    private sayFoo = () => {
        console.log('Foo')
    }

}

let foo = new Foo();
foo.sayFoo() // Error. It´s ok.

let {sayFoo} = foo;
sayFoo() // 'Foo' 

Is it by design?

[DanielRosenwasser]

Clearer case:

class Foo {
    private prop;
}
let foo = new Foo();

let a = foo.prop;
let { prop: b } = foo;
let { prop } = foo;

foo.prop in the declaration of a causes an error because prop is private. The destructuring cases don't.
