Do I understand correctly that the above code will load `woman' when being
parsed, while:

     (eval-after-load "woman" '(defalias 'man 'woman))

would wait until woman was invoked by some other command?

If yes, for performance reasons, one should prefer the latter writing, in
order to have a quicker startup time of Emacs, right?

Just wanna be sure I correctly understood (or not!) this part...

Best regards,
  Seb
