And then one would expect some rather complex logic to compute -N for $var[-N]

I don't see much of complex logic here, but $a[2] = 'a' would create a new array element if it does not exist, while $a[-2] can't. Not a big issue, but somewhat inconsistent I guess.

$n = some_incredibly_long_and_complex_computation(); //and, for real fun, sometimes it returns positive, and sometimes negative. $s = $var[$n]; If $n is a negative value, an E_NOTICE will be triggered. To not do

if ($n< 0){ //whatever } else{ //something entirely different } Prior to your string offset can be looked at being bad practice.
