Subject: Simplify singleton handling.

While working on the visual-mode code, it became apparent that our
current "singleton" implementation is unnecessarily complicated.

This simplifies it.  The keys are now required to be strings.

(Previously, they could be any object; which meant we needed to gove
objects an identity.  All of which was complicated.)
