I want completions, but I want them for things like lists of names.  The
current and past completion frameworks are very oriented to completing
code.

I figured I'd start by trying to see how they work.  My results so far
are a UMLish diagram I've added to http://wiki.squeak.org/squeak/5701.
If you want to play, I have the Dia original that generated the image.

Comments welcome.
