| Reports any references to variables which are checked for nullity | |
| in the condition of an <b>if</b> statement or | |
| conditional expression but which are not used inside the | |
| <b>if</b> statement. Usually this either means that | |
| the check is unnecessary or that the variable is not referenced inside the | |
| <b>if</b> statement because of a typo. | |
