;; Passing a Glojure `fn` to a Go higher-order function.
;;
;; `strings.FieldsFunc` takes a Go `func(rune) bool` predicate. A plain
;; Glojure `(fn [c] ...)` crosses the boundary as the matching Go
;; function value. The rune arrives as an integer code point; `(char c)`
;; converts it back for set membership.
