I'm not sure how such operation would be useful, and it definitely would not be intuitive, as $array[0] and $array[0:1] (assuming non-inclusive semantic, or [0:0] with inclusive semantics) would return completely different things. That would happen even if the array has only numeric keys! This is the main problem with this syntax - unlike most languages where it is used, PHP arrays are not vectors, they are ordered hashmaps. Sometimes this is very convenient, sometimes - like for this syntax - it is not. I think this is the major reason why such proposals failed in the past. -- Stas Malyshev smalys...@gmail.com -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
