[PHP-DEV] Can *sort functions return the sorted array ?

[Fulax]

Hi,
I wonder if it will be possible to add an extra argument to the *sort 
functions to get the sorted array directly.
At the moment I have made my own function to do this, here is an example 
with natsort :

function arrnatsort($a_array)
{
   if(natsort($a_array))
       return $a_array;
   else
       return false;
}
I think it will more convenient to simply call $array = 
natsort($array,true);, when you need to combine functions, like this :
$sSortedString =  join(',',arrnatsort(explode(',',$sString)));

At the moment, the way is to create an auxilliary function, or to make 
more steps :

$aTemArray = explode(',',$sString);
natsort($aTempArray);
$sSortedString =  join(',',$aTempArray);
unset $aTempArray;
Does it make sense to add the possibility for an extra argument ? Like 
highlight_string function, the extra argument return the string instead 
of displaying it.

Thanks in advance, and sorry for my crapy English
