I want to use collections.ChainMap, or something very like it, and I
don't want to be forced into an unnatural is-a relationship with dict if
I don't have to.

I don't think that can work, because __call__ itself is a function, and I
would need to change *its* globals. Which brings me back exactly where I
started, trying to change globals in a function to a non-dict.
