With regards to all the subsequent lambda vs defun stuff, you could also
use with-eval-after-load instead of dired-load-hook:

(with-eval-after-load 'dired
  (require 'dired-x)
  (define-key dired-mode-map "q" 'kill-current-buffer))

Actually, this does also use a lambda behind the scenes and has similar
drawbacks, but for some reason it doesn't seem to bother people as much.
