Hi, I'm in favor of disabling for consistency as well, however, I wish a warning would be emitted. Not only it would tell me that I have a potential error while upgrading to PHP 7 but also if I am using it incorrectly, which is always the case when using a scalar value. I therefor propose that: list($a, $b) = 42; list($a, $b) = "42"; list($a, $b) = null; ... generates a warning like: PHP Warning: list() expects right operand to be array, <type> given in <path> on line <line> Currently, all of the above lines wouldn't generate any notice / warning / error, however, using: list($a, $b) = []; generates the following notices: PHP Notice: Undefined offset: 1 in ... on line ... PHP Notice: Undefined offset: 0 in ... on line ... This is confusing since (to me) using an array is at least better than using scalars. Patrick
