It does. If you write a binding out to disk and then read it back in, you
should have the same instance you started with, and not a copy. That part
is fairly straight-forward: we include just the key in the data stream, and
then when reading it back in we fetch the binding using the key.

For now, the simple thing is just to use "Environment current" when we need
to lookup a binding. At some point we'll need a way to specify which
environment to use when reading objects from disk, but that needn't stand
in the way of getting this working again.
