Thanks,

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

Emiliano

Hello Emiliano,

In this case, I think you may want to use just "Str" instead of "Nil".
"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!
