Thanks Brandon,
That was what I was looking for. I'm trying it already.

Is this possible? You don't want Nil there; it's not the undefined value, it's a value of a special type. You want Str, the type object for Strings, which also serves as the undefined value (also true for other types). You can test it with `defined`. $myObject = MyClass.new(Str); then you can test $!value.defined or whatever. -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com<mailto:allber...@gmail.com> ballb...@sinenomine.net<mailto:ballb...@sinenomine.net> unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
