Even though ther eis lots of code that could need improvement, we
should not take such bad examples, but rather try to apply standard
techniques instead.

It's just a pretty common thing to do, and instead of doing the same
thing in many different ways it makes some sense to use a standard
way.

Absolute: Independent, irresponsible. An absolute monarchy is one  in
which  the  sovereign  does  as  he pleases so long as he pleases the
assassins. Not many absolute monarchies are left, most of them having
been replaced by limited monarchies, where the soverign's  power  for
evil (and for good) is greatly curtailed, and by republics, which are
governed by chance.                                  - Ambrose Bierce
