  4. IIRC luc maranget's paper was also a basis to clojure/script core.match ps: checked https://github.com/clojure/core.match/wiki/References
    comment by agumonkey · 2024-02-03 · in Compiling Pattern Matching
  5. 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…

  7. You can use this library to get pattern matching in Clojure: https://github.com/clojure/core.match/wiki/Overview

  8. I assume you mean something like clojure.core.match https://github.com/clojure/core.match ? It is available, but not used that often.

  14. Clojure has a pattern matching library https://github.com/clojure/core.match . And I think clojure is the most widely used Lisp dialect now.
