Thanks, That was it. Somtimes I get confused with the way other languages treat undefined/null/nil values.

"Str" is the "type object" for Str objects, and you can check whether it's a string like "foo" or just the Str object by checking $!value.defined. There's a FAQ answer that's about "Any", but it works the same way for "Str": http://doc.perl6.org/language/faq#What_is_%28Any%29%3F And there's the classtut that talks about this a bit more in depth, search for "type object": http://doc.perl6.org/language/classtut I hope this'll get you towards your goal. If not, just keep asking :) Have fun with Perl 6! - Timo
