you might iterate to find the path `a.b.c` (here you are iterating
just over the paths that are **actually referenced** in the source,
not all **possible** paths that could have been referenced). These
references are used for example in the [`has_any_child_of`] function,
which checks whether the dataflow results contain a value for the
given move-path (e.g., `a.b`) or any child of that move-path (e.g.,
`a.b.c`).
references are used for example in the
[`find_in_move_path_or_its_descendants`] function, which determines
whether a move-path (e.g., `a.b`) or any child of that move-path
(e.g.,`a.b.c`) matches a given predicate.
