# for ( unsigned i = 5; i >= 0; i-- ) { cout << blah[i]; }

# This fails i can never become -1. Actually, you'll have an 
# infinite loop.

If your intent is to compare "i >= 0", then your intent is to test
whether i is negative or non-negative.  It would be completely illogical
to declare i unsigned, and only beginners would be surprised that this
is wrong.
