Re: Missing ref() return possibility?

It's good to remember that when ref() is given something that is not a reference to anything, it returns an empty string. (It never seems to return "undef", even when you give it nothing at all.)

Yes. Now if only Scalar::Util`::reftype()` worked the same way. Or at least that the two were consistant. Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice. "Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."	[reply] [d/l]
