-;;; Commentary:
-
-;; This code allows accessing data stored in recursive association and
-;; plain lists using a compact notation.
-;;
-;; Consider the following list:
-;;
-;;     (setq basket '((apples . (((color . green) (taste . delicious)) ((color . red) (taste . disgusting))))))
-;;
-;; Its contents may be accessed using `fadr-member':
-;;
-;;     (fadr-member basket ".apples[1].color")
-;;     red
-;;
-;; Associated values are selected using a dot followed by a key, while
-;; lists accept an index (0-based) in square brackets.
-;;
-;; `fadr-q' is a one-argument shortcut fro `fadr-member', where
-;; (fadr-q "res.path") results to (fadr-member res ".path"):
-;;
-;;     (fadr-q "basket.apples[0].taste")
-;;     delicious
-;;
-;; `fadr-expand' substitutes ~PATH with results of `fadr-member' calls
-;; with respective arguments:
-;;
-;;     (fadr-expand "~.color apple is ~.taste" (fadr-member basket ".apples[0]"))
-;;     "green apple is delicious"
-;;
-;; `fadr-format' is like `fadr-expand', but it performs %-substitutions first:
-;;
-;;     (fadr-format "%s #%d is ~.color and ~.taste" (fadr-member basket ".apples[1]") "Apple" 1)
-;;     "Apple #1 is red and disgusting"
