<overview>
<p> There is no need for a module to import itself. A module importing itself may lead to errors as
the module may be in an incomplete state when imported by itself.
</p>

</overview>
<recommendation>
<p>Remove the import statement.
Convert all expressions of the form <code>mod.name</code> where "mod" is the name
of the current module to <code>name</code>.</p>

</recommendation>
<example>
<p>In this example the module, <code>ModuleImportsItself</code> imports itself and has an expression
referencing the module it is in as well.</p>
<sample src="ModuleImportsItself.py" />

<p>The import can be removed and the reference can be corrected.</p>
<sample src="ModuleImportsItselfFix.py" />
