<overview>

<p>Assigning a variable to itself is redundant and often an indication of a mistake in the code.</p>

</overview>

<recommendation>

<p>Check the assignment carefully for mistakes. If the assignment is truly redundant and not simply

incorrect then remove it.</p>

</recommendation>

<example>

<p>In this example the programmer clearly intends to assign to <code>self.eggs</code> but made a

mistake.</p>
