Hey Natan its seems that subset does not fit the bill in my case because the values that I'm replace are based on a pred

(tranform [:one (pred keyword?)] (fn [_] [[1 2] [3 4]]) {:one #{:two}})

Ok managed to solve it

Since my kewords are days its closed set (so subset works) but id be curious on how you can use pred to substitute values

@narkisr you would need to iterate over all the values and check the predicate against each value

ALL isn't currently implemented for sets though

you could either use a vector there instead of a set or make an ALL-SET-ELEMS navigator

(or open a pull request to extend ALL to sets)

Thank you Natan, ill take a look on what it takes to add support for that

@narkisr need to extend AllTransformProtocol to PersistentHashSet

@narkisr actually just realized that ALL already handles sets via the default case, it's just not optimized like the other data structures
