And the same with most !-methods (they return > nil when nothing was changed). That always bothered me, since I lose my method chaining with ! methods. Like this: line.strip!.downcase! must be line.strip.downcase to work properly. But then you lose some efficiency. I'd prefer that ! methods returned 'self'. In the *rare* case that I need to know if something changed, I'll use == or something. RCR in the making? Dan
