;; Currently this package is non-deterministic due to random generation in
;; some of the primitives. This is marked as a TODO in the source code, but
;; per the maintainer this package almost solely exists for the purpose of
;; building CBQN at this point, and therefore is not a high priority. Git
;; reports this here:
;;
;; src/BQN/types/callable/builtins/fns/EpsBuiltin.java:45:71:
;; …<snip> // TODO these (and in ⊐) shouldn't be random numbers
;;
;; Reported Upstream Here: https://github.com/dzaima/BQN/issues/14
;;
;; This issue therefore means that none of the packages for bqn can be checked
;; for non-determinism at this time, as dbqn is a prerequisite for all of
;; them.
