As I posted on Reddit:

It might also be good to mention Injest

https://github.com/johnmn3/injest

Which makes transducers more ergonomic to use if you are like me and use threading macros everywhere

Would be curious to hear how others feel about it

Another great library that decidedly reveals transducer value: https://github.com/cgrand/xforms

these look great to me. would there be a downside to adding them to core?

Macros that rely on parsing and rewriting their bodies are great way to introduce bugs. The regular threading macros work well enough because they are simple. More complex rewrites don't compose with other macros.

Clojure authors are quite conservative about adding such opinionated instruments into the language, especially when they come from outside. But fortunately, being a Lisp allows Clojure to add such language modifications with libraries without forcing those modifications upon every user of the language.

That’s true, but:

1) they did add threading macros, which are very popular, and these seem to serve a very similar purpose for transducers. You could argue their inclusion would make the language a little more uniform even.

2) There is precedence for doing the same operation with different mechanisms, like map vs mapv, so the change fits in nicely in that sense

3) as the article points out (edit: just realized you are the author, heh, hello!), transducers often have better performance than alternatives. I think it makes sense to highlight them and encourage their usage as much as possible. The more high performance code in the wild, the better. Even just introducing new ergonomics that facilitate their usage will influence that.

This is sort of true, but it doesn't scale well. You quickly end up having a very verbose `ns` declaration at the top of every file as you try to extend your Clojure

To cut down on the noise, you can coalesce all your extensions into one `ns` but it's not technically feasible with `core` and needs to be done with another library:
