A curated collection of answers that Rich gave throughout the history of Clojure

Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

  • The link in the table of content jumps at the copy of the answer on this page.
  • The link on the answer itself points back at the original post.
