Why is MaybeChannelBound callable?
<p>The Queue class in the python kombu library inherits from MaybeChannelBound, which in turn implements the <strong>call</strong> method (making it callable). The <strong>call</strong>() method itself is a thin wrapper around the bind() method.</p>

<p>It is not clear why this was done, as calling the bind() method seems (to my simple mind, at least) to be clearer and more descriptive of the intent of the function.</p>

<p>Why would somebody use the <strong>call</strong>() method in a situation like this?</p>
