Error accessing private property in destructuring with computed property name #26356

TypeScript Version: 3.1.0-dev.20180808

Search Terms: private string access

Code

class Foo {
    private bar = 1;
}
let foo = new Foo();

foo.bar; // error as expected
foo['bar']; // no error as expected

let {bar} = foo; // error as expected
let {'bar': bar2} = foo; // error (expected?)
let {['bar']: bar3} = foo; // error (expected?)

Expected behavior:

#26328 states that accessing non-public properties via element access with string literal or late-bound name is intentionally allowed.
To be consistent that should also apply to destructuring with computed property name or quoted name.

Actual behavior:

Errors as described by the inline comments.
