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]; //a few hundred lines later, buried somewhere else if ($n < 0){ //whatever } else{ //something entirely different } Sooner or later, somebody will do that, and I really don't want to have to un-tangle all that mess to figure out if $n is positive or negative for the sake of saving a few keystrokes... -- brain cancer update: http://richardlynch.blogspot.com/search/label/brain%20tumor Donate: https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=FS9NLTNEEKWBE
