It is good to hear such announcements encouraged.
I have often missed some ideas from Clojure and Racket in guile and recently had an idea to create a library that would bring those ideas in one place. I have defined macros that bring Clojure or Racket forms into the several projects I've used guile in.
I wonder if some people would be interested in having such a module - something similar to what Rackjure (
https://github.com/greghendershott/rackjure) is for Racket
I imagine that this module could become focus of contributions and evaluation and some features could either make into Guile standard library or be collected as another language hosted by Guile VM.
An example usage of such library would be this:
(use-modules (borrow clj)) ;; imports some Clojure forms, like: if-let, when-let, if-not, when-not
