Multiple enums in datomic

Please see the James Bond example in the Tupelo-Datomic library. In short, when adding multiple enum attributes you need to wrap them in a set instead of a vector:

; Create some antagonists and load them into the db. We can specify some of the ; attribute-value pairs at the time of creation, and add others later. Note that ; whenever we are adding multiple values for an attribute in a single step (e.g. ; :weapon/type), we must wrap all of the values in a set. Note that the set ; implies there can never be duplicate weapons for any one person. As before, ; we immediately commit the new entities into the DB. (td/transact *conn* (td/new-entity { :person/name "James Bond" :location "London" :weapon/type #{ :weapon/gun :weapon/wit } } ) (td/new-entity { :person/name "M" :location "London" :weapon/type #{ :weapon/gun :weapon/guile } } ) (td/new-entity { :person/name "Dr No" :location "Caribbean" :weapon/type :weapon/gun } ))
