Be careful. Once you grok Emacs, you may never be able to use another editor again.

(defun hello (&optional name)
  "Say hello, optionally to NAME."
  (let ((greetee (or name "World")))
    (concat "Hello, " greetee "!")))

Exercism is a great website

The reviews are incredibly helpful because they help me see things that I missed, learn about new ways and sometimes interesting discussions that can add a fun twist to maybe a simple problem.

Relaxed. Encouraging. Supportive.
