1) This code:
<?
class Priority {
const DEBUG = 0;
const INFO = 1;
const WARN = 2;
const ERROR = 3;
const FATAL = 4;

const MAX_PRIORITY = FATAL;
}

class ExtendedPriority extends Priority {
const REMOTE = Priority::MAX_PRIORITY + 1;
const URGENT = parent::MAX_PRIORITY + 2;
}
?>

results in this error:

PHP Fatal error:  Unsupported operand types in /test.php on line 13

Shouldn't class constants support simple expressions ?

2) Also, this code:
<?
class test {
const TEST = "hi";
const TEST1 = self::TEST . "ih";
}
?>
Results in segmentation fault.

So It's a compiler bug if it not complaining abount contant expressions...

P.S.: I remember that on this list someone posted a patch to allow these
kind of expressions. I think at that time it was commited to CVS. Are you
shure that these expressions won't be allowed ?
