You can't instantiate a role directly, so if a Blob is declared as a role you can't just instantiate one directly, isn't that how it works? Either way it seemed to be getting treated differently. -- Darren Duncan

$ 6 'role A {}; my $a = A.new; say $a'
A.new()
You *can* instantiate a Role directly. See above.
