One thing that always made me a little sad about transducers was how map lost its ability to iterate multiple collections in parallel. This is actually my favorite feature of map. For example:
(map + (range 5) (range 5 10))
=> (5 7 9 11 13)One somewhat practical use of this is if you want to compare two sequences, pairwise, using a comparator. Though I wish that every? took multiple collections, this is an adequate substitute:
| (ns bakusatsu | |
| (:refer-clojure :exclude [+ -]) | |
| (:require [clojure.spec.alpha :as s] | |
| [clojure.spec.test.alpha :as stest] | |
| [clojure.core :as core])) | |

"Yet, by (someday) providing all the (supported) APIs, Joker enables higher-level, Clojure-like, APIs (that call these low-level API wrappers) to be written without requiring changes to the Joker codebase or executable itself."
I’ll try to address what I think might be unclear: normally, to make Go APIs available from Joker code, one might write a custom Joker source file, such as std/os.joke, perhaps accompanied by a std/os_native.go file, and then rebuild Joker. Alternately, one could add a namespace to core/data/some-namespace.joke and have it call new Go code, calling the desired APIs, provided in core/procs.go (or similar), which can be more complicated due to needing to modify other files…and then rebuild Joker.
Either way, the source code of Joker has to be modified, and Joker rebuilt, so the API can be called. gostd is intended to provide out-of-the-box access to all the Go standard-library packages via very low-level Joker access.

Happy to announce that Rum 0.12.0 has been released.
A major change in this release is Daiquiri — reworked fork of Sablono. The reason we went with a fork is to own the compiler/interpreter. Daiquiri removes input field wrappers, this was causing weird bugs with jumping caret. Similarly to Sablono, Daiquiri makes use of ClojureScript's type inference to reduce number of generated interpret calls when compiling Hiccup. This applies to primitive types such as number, string, array and function, and also anything that is hinted as js/React.Element, Rum components include the type hint implicitly.
Sablono's input wrappers exist because some ClojureScript React wrappers have their own update scheduling mechanism built on top of js/requestAnimationFrame which doesn't play well with input fields. In this release we've removed Rum's scheduler, which allowed us to remove input wr
