Everyone should be using the standard CSV notation... which unsurprisingly is commas. Using pipes should be restricted to when your data is peppered with commas. > b) forgetting to ascribe "/\|/" in anything like a RegEx > a la /|/ in any of it's manifestations.... Hey, I remember to backslash this if I know it's a regex. split is a pain because you can easily forget it ALWAYS works with regexs: split '|', $string does not split on pipes, but is exactly the same as: split /|/, $string and hence the magic of using single quotes doesn't work as you'd expect. It does get you out of other trouble though: s'$%@|'replacement'; where you'd otherwise spend all day backslashing things.
