sorry, i can hardly found the thread. can u give me sone hint on the
subject so i can search it?

i don't thinik if good to write such code nor to speed it up by
converting it in compile time

looks good. but not allowing $binary . $unicode makes some problem
with the old code in index.php:
require_once($_SERVER["MY_PROJECT_DIR"] . "/lib.php"); where
$_SERVER["MY_PROJECT_DIR"] is import from httpd(such as apache)
mod_setenv
one have to modify it to:
require_once($_SERVER["MY_PROJECT_DIR"] . b"/lib.php");
and such code cannot even parsed under <php6
or use "declare" for even 1 string.
declare (encodig="binary") {
require_once($_SERVER["MY_PROJECT_DIR"] . "/lib.php");
}

able to declare for binary too...
unicode_semantics is much less useful/harmless if most of the script
files have declare at the top of the code :)
i wonder what the world will be with the following code if there's no
implicit(auto) cast:
function test($a, $b = "me") { return "$a is a friend of $b"; }
$x = u"x";
$y = b"y";
test($x);
test($y);
i see no reason not to allow $binary . $unicode, except for
performance (maybe there was in the discussion thread). it's better to
use a E_STRICT or profiler etc to tell u that a implicit cast is occur
for performance only.
