<overview>
<p>
Using a named argument whose name does not correspond to a parameter of the <code>__init__</code> method of the class being instantiated, will result in a 
<code>TypeError</code> at runtime.
</p>

</overview>
<recommendation>

<p>Check for typos in the name of the arguments and fix those.
If the name is clearly different, then this suggests a logical error.
The change required to correct the error will depend on whether the wrong argument has been
specified or whether the wrong class has been specified.
