Messing around with things and trying to find a good way to make a string reference-able...

ReferencableString.js

var StringReference = function(scope, str) {
    if(str===void 0) { str = scope; scope = window; };

    Object.defineProperty(scope, "__"+str, {
        configurable: true,
        enumerable: false,
        get: function(){
            return scope[str];
        },
        set: function(val){
            return scope[str] = val;
        }
    });
 
    var ret = new Function();

    ret.prototype.valueOf = ret.prototype.toString = function(){
        return this.get();
    };

    ret.prototype.set = function(val) {
        return scope["__"+str] = val;
    };

    ret.prototype.get = function() {
        return scope["__"+str]
    };

    return new ret();
};

The nice thing about the "old fashioned," manually written getter/setter objects was that they were portable regardless of their value.

Using myVar.getValue() and myVar.setValue() would always update the variable in the initial scope back when we declared the myVar object, and we could lug it around wherever we needed to. Unfortunately, we cannot do this with native setters/getters...
