Extension method for python built-in types!
<p>is it possible to add extension method to python built-in types?
I know that I can add extension method to defined type by simply adding new method by . as following:</p>

<pre><code>class myClass:
    pass

myClass.myExtensionMethod = lambda self,x:x * 2
z = myClass()
print z.myExtensionMethod(10)
</code></pre>

<p>But is any way to adding extension method to python built'in types like list, dict, ...</p>

<pre><code>list.myExtension = lambda self,x:x * 2
list.myExtension(10)
</code></pre>
