I was not able to reproduce this behavior. With the program you provided, I got error Arity mismatch, expected 2 args: (ISet-length $IS1)
.
Getting rid of the second parameter to ISet-length, the program runs as expected.
(sort ISetBase (Set i64))
; Reify set
(sort ISet)
(function IS (ISetBase) ISet)
(function ISet-length (ISet) i64 :unextractable)
(rule ((IS x))
((set (ISet-length (IS x)) (set-length x))))
(let myset (IS (set-of 2 4 1 4 -1)))
(run 100)
(check (= 4 (ISet-length myset)))
Maybe you are using an older version of egglog?
Trying to build a smaller repro from the toy example, this leads to the following error with
egglog 0.1.0
