hm, at r182007, it already fails.
So there's issue before r182007.

The issue looks like that.
In chai.js, we call

function Assertion(...) {
    flag(this, '...', ...);
    flag(this, '...', ...);
    flag(this, '...', ...);
}

function flag(obj, ...) {
    accessing obj.__flags become error (obj is undefined)
}

function expect(...) {
    return new Assertion(...);
}

I guess
1. accidentally accessing incorrect location of arguments (`obj`).
2. accidentally `this` becomes undefined.
