Re: Support negative indexes for arrays and strings

Yes, typo! sorry. $array = array(1001, 1002, 1003, 1004); $number = $array[-1]; // => 1004 $array[-1] = 1005; $number = $array[-1]; // => ???? Looking at the resulting code, I would like to point out also that it's extremely misleading... because $array[-1] references two completely different elements depending on whether you're reading or writing the value... unless $array[-1] = 1005 would actually overwrite the last element in the array - in which case it gets even more dangerous, as well as breaking backwards compatibility...
