Description:
------------
$$c is an array 
$$c[0] is not defined 
($$c)[0] is a syntax error 
 
There seems not way to directly access the content of a 
referenced array. 
 
My PHP version is 4.3.4-4 of Debian unstable 

Reproduce code:
---------------
$tmp=array("hello world");
$c="tmp";
$a=$$c; # works
echo $a[0]; # works
echo ($$c)[0]; # should work
echo {$$c}[0]; # would not mind if this was an alternative

Expected result:
----------------
"tmp" 

Actual result:
--------------
syntax error
