in reply to "or die" versus "|| die"
The perlfaq is and has been maintained by several people, so you see a lot of different styles and conventions. Rather than enforce a particular style, I let the answers show that there is more than one way to do things, although I have also started noted the authors of each answer.
The "best way" is up to you. The "or" version generally works out for people who don't like parentheses (since they don't use the parens' supreme precendence to define the order).
