The implementation of `multi-path` is a nice example of the use of `variable-pathed-nav`.

The implementation of `collect` is a good example of how `pathed-collector` can be used.
```clojure
=> (defpathedfn
collect

(pathed-collector [late path]
(collect-val [this structure]
(compiled-select late structure))))
(defpathedfn collect [& path]
