in reply to Perl 6 feature that scares me the most:

As of right now, I am the singular voter for variable traits. I just don't really see it, yet. I understand it, when it is used like:
my DVD $matrix is Scalar; # or my DVD @disks is Array; # or, even my DVD %disks is Hash;
I just get a little wary when I see something like:
my DVD $matrix is Media; # or my CD @disks is Media;
I just don't know how that is going to work. For example, I know what this would do:
my DVD $matrix is Scalar; $matrix = "I know Kung Fu";
But, I have no idea what this does or how to define what it does in the whimsical world or Perl 6:
my DVD $matrix is Media; $matrix = "There is no spoon";
Anyone have insight?

    And now you can also do this. *grin* All that this does is separate the interface from the implementation.
