proposal: Object Members

[Ranando King]

@ljharb: It seems you now understand what I was trying to say. Sadly, I'm
not always the most eloquent.

The intent of my proposal is to provide both member fields and privilege
levels to the `class` keyword, and the equivalent for object literals in a
way that meets with both an intuitive declaration style, and a reasonable
access notation that breaks as little as few as possible of the developers
expectations of what can and can't be done.
