Yeah, upon actually walking through my desired example, I found that
the Symbol/Weakmap is irrelevant. Here's what I was thinking, using
only existing stuff:
```
(function(){
var shared1;
function ForeignObject() { /* Uses shared1 somehow */ }
ForeignObject.setSharedSecret(val) {
shared1 = val;
}
})();
(function(){
var shared2 = "the real secret";
function MyObject() { /*...*/ }
MyObject.exposeSharedSecret(cb) {
cb(shared2);
}
})();
MyObject.exposeSharedSecret(ForeignObject.setSharedSecret);
```
