Hi everyone. I just thought of some ways to standardize this: 1 - Create an RFC to create an "uninitialized" construct/function to make this check; 2 - Ask Larry and Ilija to include an "is uninitialized" pattern into their wonderful Pattern Matching RFC (https://wiki.php.net/rfc/pattern-matching); 3 - Create a PSR to create this "Uninitialized" class and constant standard to PHP. I would go for option 2. Best regards, Erick
