This should work

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question: 

use Set::Scalar;
use Set::Scalar::Valued;

$foo = Set::Scalar::Valued->new;
$foo->insert("bar", Set::Scalar->new);
$foo->value("bar")->insert("baz");

# But I get 'Can't call method 'insert' on unblessed
# reference at test.pl line 6.' What's the deal oh wise
# ones?

    I think you need to create your "bar" object explicitly before you insert() it into "foo". (An "unblessed reference" is something that you're treating as an object before Perl knows it's an object. See bless.)
