Interesting memo for i++ and ++i.
If (i++ < i) // absolutely true;
If (i -- > i) // absolutely true;
if (++i == i) // absolutely true;
if (--i == i) // absolutely true.
If (i++ < i) // absolutely true;
If (i -- > i) // absolutely true;
if (++i == i) // absolutely true;
if (--i == i) // absolutely true.
