Description:
------------
when passing func_get_args() as second parameter of a 
function, it complains.

foo('foo', func_get_args());
Fatal error: func_get_args(): Can't be used as a 
function parameter in /Users/iboom/Desktop/Journaux/
2004.04/fonctions/arg_defaut.php on line 23


foo(func_get_args(), 'foo');
is OK tough.

So, it won't work with
print join(',',func_get_args());
array_map('foo',func_get_args());

Reproduce code:

function a()
{
	print func_num_args().'<br />';
}

function b()
{
	$dd = 123;
	a(func_get_args());
	a(func_get_args(), $dd);
	a($dd, func_get_args());
}

b('Hello World');

Comment:

I tested the code with same result on 4.3.10-1.dotdeb.0 and 5.0.3-1.dotdeb.0.

I think all the lines should fails on none of them.

Can't see anything in the documentation about this.

Damien, the docs say: "This function cannot be used directly as a function parameter. Instead, its result may be assigned to a variable, which can then be passed to the function.", so don't use it as a parameter.

So there is no bug, and the docs already describe it -> bogus.
