This discussion is equivalent to the one that we just had. Read the thread
"[PHP-DEV] Implicit isset/isempty check on short-ternary operator".
Also the "$var = var_set($_GET['var'], $_POST['var'],
'default');" syntax
you propose would be equivalent to (as per previous discussion):
$var = $_GET[?'var'] $: $_POST[?'var'] $: 'default';
(The syntax might also be [?'var'], ['var'?] or different).
