I did. But for Cherry the first introductory line says - "this is experimental" and has been the same state for 2 years (IIRC). Squint is also "under development" and is more "mutable" by nature. Also, both of them are maintained (largely) by the same person (who is really good btw) but I am also confused why there are 2 experimental projects of the same nature by the same devs. Anyways, all this does not fill me with confidence where I can say that "hey lets try to build something serious with this tech stack".
I agree, these are highly experimental projects, more like POC's and not something to actually use for important work. I don't know why people are so often recommending all these myriad different Clojure/Script runtimes/interpreters, many of which are not fully baked.
