Right, this kind of fix is a losing proposition. I'd prefer to see a proxy around the Scalar returned by .VAR that restricts what can be done with it, so it can't escape into the wild --- because once a Scalar can be accessed directly, you've broken the type system. -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com ballb...@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
