You misunderstand the proposal a bit. In `x::y`, the y is an object that is asked to respond in a special way. When `y` is a WeakMap, it responds to `x::y = z;` by calling `y.set(x, z)` on itself. You can store whatever you want in there; the `z` value can be anything, including numbers or booleans. But the `y` object needs to be something that knows how to respond to the bind operator. (Similarly, if `y` is a function, by default it responds to `x::y(z)` by calling itself with its `this` set to `x`. This makes it act similarly to `x.y(z)`, but without having to actually define `y` as a property on `x`.)
