Hi everybody,

A while back Levent mentioned that we ought to initialize the references
dictionary in an Environment eagerly rather than lazily. (

)

I think this is a good idea, because it makes Environments more similar to
the existing single-namespace system. It's possible to reflect on the
visible bindings in a single place, rather than have them magically appear
when you try to use them. However, it means that we'll need to modify the
references dictionary in response to changes in other environments in order
to keep it up today. That implies hooking into SystemChangeNotifications,
and modifying them to include environment information.

I've started to work on this change, and I hope to fix the above issues
along the way. I've also run into some semantic issues that need some
clarification, which I'll bring up in separate messages.
