This seems like a trick. Many feature could also be remove, such as I refered in RFC: Null coalesce "??" and Ternary Operator "?:" And the trick is trick. If you want to unpack nested array. list($a, list(list($b))) = $array Then you might need a new trick to do that. You know we have default for function declaration: function func($a='default') {}; and almost all language have the feature, it is easier to understand from my perspective. > compared to having more functionality added to the 'list' magicness. > > cheers > Dan > -- Reeze Xia http://reeze.cn
