What if I have private values I want to access programmatically? Ie. fields = ['#foo', '#baz', '#bar']; fields.forEach(field => { this[field] = frobnicate(field) }); ?
I don't know what the spec's solution for that would be, but what you've typed would not work. Specifically because when I say `this.#foo` it is not a property on the object named "#foo". It is just the syntax for looking up a private field referenced by the literal #foo.
