ifsetor like expression in php6

hi, i just found the new ifsetor like construction in php6. It left me the question why php has to throw an E_NOTICE when the variable is not set. This is basicly because that actually is the meaning of this construction, checking if the variable is set and if it isnt give back a standard value. Of course i know this construction can be (mis)used with an Boolean check ($var===$var2), but this does not make much sence either because TRUE will then be assigned to the new variable if the expression evaluates to TRUE (but please correct me if theres a real use for this). So in any case it would be better to remove the Boolean check feature and make it a simple ifsetor() without the E_NOTICE again. For those of you who have not heard of it heres an example: <?php // If $_GET['foo'] is set, then its value will be assigned to $foo, // otherwise 42 will be assigned to $foo. $foo = $_GET['foo'] ?: 42; ?> Greetings Sebastian
