Reports assignments and function calls where the name of the variable to which a value is assigned or the function parameter does not seem to match the name of the value assigned to it. For example:
int x = 0;
int y = x;

or
int x = 0, y = 0;
Rectangle rc = new Rectangle(y, x, 20, 20);

The configuration pane allows to specify the names which should not be used together: the error is reported if the parameter name or assignment target name contains words from one group and the name of the assigned or passed variable contains words from a different group.
