Undefined Constants behavior in PHP6

I was wondering if someone already think about modifying the actual behavior
of undefined constants in php6.
I'm desperate with some

if(DEBUG) print_r($_SESSION);

and lot others case -

Is there a possibility undefined constants ( strings ) return "null" :x ?
I do not think it's a mistake, since echo "{$array[foo]}" is not good and
"{$array['foo']}" is

and what's wrong with the following syntax?

if(defined('DEBUG')) print_r($_SESSION);

I don't think there's a need to change anything here…

Just make sure you always set DEBUG, shouldn't be too hard if your code
has any structure ;-)

It's not always a structural issue :/
I'm sure non defined string interpretation is a bad thing

I'm not a php core writter, but it have to be, even a little, more
complicated to use undefined constants as there "string" value, than as
"null"

Maybe i'm the only one thinking that way.
I'll try to handle this by myself with parsekit & runkit ...

It is

I'm sure non defined string interpretation is a bad thing
it is definitely a bad thing, but it is a documented bad thing and I
believe there are still some scripts which rely on this

use of undefined constants produces a E_NOTICE
you can catch these in error-handler while debugging and fix the
structure of code accordingly.
