How can I get a list of arguments _expected_ by a function?
<p>I need to be able to interrogate a function/method and get a list of the arguments which that function <em>expects</em>, from <em>outside</em> the function, <em>before</em> the function is called.</p>

<p>So not argument values, but a list of expected argument 'slots' per say.</p>

<p>Possible?</p>
