I was under the impression that static_cast and the old C-style cast were
the same? If this is the case, you may already be burning in hell and
don't even know it. :) 

When the Programmer's FAQ says "avoid dynamic_cast" (I haven't seen this
FAQ), I would hazard it means "think about why you need the cast at all". 
When casting down the inheritance tree (eg casting a QWidget * to
QPopupMenu *), dynamic_cast is the best way to do it. For anything else,
use C-style or static_cast. (except when you are just removing const; then
use const_cast).
