Weak referencing is pretty well explored, I think.  It's intentionally not
supported for the most part in JavaScript, because most weakref features
expose garbage collection behavior to scripts.  Web APIs don't do that.

This approach exposes GC behavior, making it possible to write code that
behaves differently depending on GC.
