Does anyone else think that making ":=" a non-expandable operator is a good 
thing? I like the idea of knowing for certain what an assignment statement 
does. It gives me an anchor to start from.

Once E converts to immutable collections, there will be no built-in types 
that benefit from this expansion. I think you should get rid of it.
