Obligatory, mutable global variables are evil.

As opposed to immutable variables

Or mutable constants...

int const golden = 1.618;
int* non_constant = (int*)&amp;golden;
golden = 1.61803399;

Casts are totally not a danger that should require a comment explaining safety…

And more generally mutable aliasing references of any sort are evil. Doesn't mean they're not useful, just that you need magic protection spells (mutexes, semaphores, fancy lock-free algorithms, atomics, etc) to use them safely. Skip the spell or use she wrong one, and the demon escapes and destroys all you hold dear.
