clojerl VS core.match

Basically, you take a programming language and make it work on a platform that meant to be programmed using a different PL. Clojure is hosted by design - it's not Java, but can be used to program for JVM. It ain't Javascript, but can be used to target nodejs and browser; not an [official] CLR language, but you can write .Net programs. You can use Clojure to make Flutter apps with ClojureDart. You can integrate Python into Clojure with libpython-clj. Or write Clojure to target Erlang/OTP; or Rust; or R; There's even a clojure-like language for Lua - Fennel.

There's something about Clojure people like so much, they want it to work atop any platform.

But there are also unofficial implementations—i.e. not JVM, JS, .NET—of Clojure for other host environments, e.g. Clojerl. And of course nearly everything /u/borkdude touches interops with something in some way.

Tail call optimization/elimination isn't a property of functional languages - there are tons of non-functional languages with it, like Lua or even C, when compiled with -O3, to name a few. Besides, Clojure is a hosted language, so it shares the platform characteristics, and recur is a language-way of providing a construct for tail call looping. Clojure on BEAM for example, supports tail call elimination, because BEAM does. And Beam is a quite functional environment ;)

Clojerl: an implementation for the Erlang VM. The reader conditional is :clje.

There's also an unofficial BEAM VM implementation

IIRC luc maranget's paper was also a basis to clojure/script core.match

ps: checked https://github.com/clojure/core.match/wiki/References

If you take a look a this library which is an "official" library you will find three snippets of code for adding the dependency to your project and some with a very strange syntax.

I think Clojure has benefited from matching being kept out of the built-in stdlib. https://github.com/clojure/core.match is a plug-in and as a result we've had lots of cool data traversal/matching DSLs come around and evolved user communities with time such as Meander and Datascript not to mention the parsing applications of the schema systems (spec & malli).

Why not just use core.match? https://github.com/clojure/core.match
