We haven't yet separated the semantics of {} and []. It was always planned but never done.
I'll put it on my TODO and hopefully will find some time to look into it.

Ex. $a = "123"; echo $a[-1]; // would print 3 I don't think we should do this for arrays, since -1 and similar are valid array keys, which means adding this support for arrays would break BC. this, coupled with splicing, is very useful in python. i believe it would be very useful in php as well. agree with sterling's suggestion - it would enable all of the functionality, rather than some. paul -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
