various attempts at implementing transparently composable Promises

[ahamid]

Gave a shot at implementing this. One desirable (although possibly not mandatory) characteristic would be returning the "previous" value the variable held, while currently holding a Promise value. I wasn't able to follow all the conditions under which this value gets set/returned; i ended up overriding this.value via a setter/getter, although I wasn't successful in capturing/intercepting all possibilities.
Alternative is to just return undefined whenever the Variable holds an unfulfilled Promise, which will work as long as the consuming code knows how to interpret this.

Update: updated with a simple helper that just does the decoupled subscribe/put

Here is my work so far, I have to do so more work on making transforms not cache stale synchronously retrieved values.
