Is "logger" some function that exists in Emacs, or should I simply
make it?

(defun rcd/emacs-lisp-log (log)
  "Allows functions to log their usage"
  (let* ((function (second (backtrace-frame 5 nil)))
	 (timestamp (format-time-string "%Y-%m-%d-%H:%M:%S"))
	 (log (format "%s %s %s\n" timestamp function log))
	 (save-silently t))    
    (with-temp-buffer
	(insert log)
      (append-to-file (point-min) (point-max) *emacs-lisp-log*))))

(defun rcd-space ()
  (interactive)
  (rcd/emacs-lisp-log "SPACE")
  (self-insert-command 1 32))

Then I made global-set-key SPC to rcd-space and now I log each SPACE
as *emacs-lisp-log* is like ~/tmp/lisp.log. Typing is not obstracted.

It is useful for self supervision.
