Research direction
Start at query.cljc:546 in bind-by-fn and reproduce the two query snippets from the issue. Trace why the rule form reports an unknown function while the direct form succeeds; done means function input in query rules behaves consistently with the direct query without that error.
Written by the indexing model from the issue text.
Description
I could easily be missing something, but to my current understanding, the intended behavior between the two code snippets below should be identical.
(d/q '[:find ?int
:in ?intersection
:where [(?intersection #{:a :b :c} #{:c :d :e}) ?int]]
clojure.set/intersection))
;; => #{[#{:c}]}
(d/q '[:find ?int
:in % ?intersection
:where (intersection-rule #{:a :b :c} #{:c :d :e} ?int)]
'[[(intersection-rule ?s ?t ?int)
[(?intersection ?s ?t) ?int]]]
clojure.set/intersection))
;; => Execution error (ExceptionInfo) at datascript.query/bind-by-fn (query.cljc:546).
;; Unknown function '?intersection__auto__1 in [(?intersection__auto__1 #{:c :b :a} #{:e :c :d})
