Yep, this is bad IMHO. Your concern is valid I think, but your "solution" isn't a good one. Why not just use a module like Damian's Quantum::Superpositions? (i.e. create a Null object that propigates the unknowability of the value through operations) If it's part of the standard distribution, then those that want null in perl can have it and we don't have to live with Yet Another Keyword. -Scott -- Jonathan Scott Duff [EMAIL PROTECTED]
