@peterhfmnn You want to use '#{}
(let [f (r/find
#{'a ^& '#{}} :yes)]
[(f #{'a 'b}) (f #{'a})])
;=> [nil :yes]đź‘Ť 1

Awesome! I somehow wasn’t aware that (= #{} '#{}), but this makes a lot of sense!

I have mixed feelings about this though and, in the next version of the library, I think this will be an optional semantic because I think it is slightly confusing. Mostly, I did this to make matching on those data types more Clojure friendly.

Set patterns represent subsets the same way map patterns represent submaps.
