I was being silly and did just appended blindly to a single slice which resulted in duplicates. Using a set seems like the cleanest option. On the API boundary, a plain slice is returned (I don't like returning 3rd party types from a public API..). There's also a new function to list all actions in a directory what I think the majority of users would like (except when parsing patches).
