This check looks for variable assignements that are either overwritten by other
assignments or where the variable is not used subsequently.

Both the $myVar assignment in line 1 and the $higher assignment in line 2
are dead. The first because $myVar is never used and the second because
$higher is always overwritten for every possible time line.
