Clojure isn't a Common Lisp implementation, it's a different Lisp dialect with an emphasis on immutable data and interacting with host systems like the Java VM.

This is Clozure: https://ccl.clozure.com/

I used Clojure for a few years on two jobs, but in this context I did intend Clozure Common Lisp.

I also wrote a small side project in Clojure about ten years ago http://cookingspace.com/ that I used to track nutrients as percentage of daily requirement in my recipes.

Today I learned!

No, Clozure is correct. OP is referring to Clozure CL, not Rich Hickey's Clojure.
