OK. I think I am starting to get it. I've always found it
disturbing that for_each_*ref*() has a "submodule" variant.
Instead, the plan (outlined in the discussion from yesterday that
triggered your posting this series) is to give an API to request a
"ref-store", and then ask that object to iterate over refs, and
these steps get us closer to that goal, because the "to enumerate
these" won't have to know what set of refs a ref-store contains. If
you want to iterate over refs in a submodule, you grab a ref-store
for the submodule and ask it to iterate. Iterating over refs in
another worktree, you grab a different ref-store and ask it to
iterate using the same API.
Sounds like a good direction to go.
