[ ... obj! ... key! arg1! ...! argN! ] -> [ ... obj! ... retval! ]

=summary
<p>Call <tt>obj.key</tt> with <tt>nargs</tt> arguments, with <tt>this</tt>
binding set to <tt>obj</tt>.  The property name and the function arguments
are replaced by a single return value; the target object is not touched.
An error during the function call is not automatically caught.</p>

<p>If the target function is not strict, the binding value seen by the
target function may be modified by processing specified in
<a href="http://www.ecma-international.org/ecma-262/5.1/#sec-10.4.3">Entering Function Code</a>.
</p>

<p>This API call is equivalent to:</p>
<pre class="ecmascript-code">
var retval = obj[key](arg1, ..., argN);
</pre>

<p>or:</p>
<pre class="ecmascript-code">
var func = obj[key];
var retval = func.call(obj, arg1, ..., argN);
</pre>
