The full generalization of this is dynamic scoping, as you may know.
There's a discussion of the implementation in emacs in the emacs
manual. Not thread safe but can be made so with an immutable binary
tree, eg the Map module. You could map either strings or polymorphic
variants to your config value type, probably a regular variant. I'm not
sure how much of a performance savings polymoprhic variants would be
over strings.
For a couple of other approaches see
