[wp-hackers] Child Themes in OOP flavour

[Nikola Nikolov]

What Thomas suggested, except for maybe I would hook onto the
'after_setup_theme' hook with priority 0 - the reason for this is that this
way you wouldn't be able to make a mistake - as in let's say that for some
reason you include another vital file(containing a class definition) after
you call your custom action - this way, you can get a fatal error(well
obviously that's something you can't miss, but still).

Anyway - my thinking is that it might be better to do extensions in the
child theme after the theme is completely set-up(this means all code in
child and parent theme's functions.php completes executing.
