No conclusive agreement on the name "dor" or "err" Why do we make things difficult on ourselves and do silly things like make the "defined or" look like, err-or? Is it an error? > > 2. No agreement on the state (builtin keyword or weak keyword) Maybe stay away from overloaded terms like "err" and you'll get some more agreement. "dor" is fine with me. "err"? >_>... And IIRC, "//" is not a logical operator; it's more like assignment shorthand. So does it even need a lower precedent "word" to represent it? In what cases might this be useful? Maybe we can consider the shorthand "ass" (for assignment) in this case? Cheers, Brett > > History: > > ? "err" as low-precedence defined-or was introduced somewhere between > 5.8 and 5.10, probably mid 2002. The first cleaned-up patch I found > was from 26-07-2002.
