;; excerpt of foldable multireducible impl | |
;; | |
;; - introducing concept of mutable iterator, which is | |
;; much faster than seq | |
;; - this is for a (yet unreleased) custom patched clojure, | |
;; where clojure.lang interfaces can behave like protocols | |
;; - map is reducer variant, thats why I have to call seq on it | |
;; - seq is patched to support any reducible, not just Seqable | |
