in thread It's a dog, but what kind? (polymorphism , in Perl OO)

I see where I went wrong. I read the above as bless $self, $class instead of bless $self, $breed.

In any case, I still think that if you want this to be a good tutorial on polymorphism, some of the subclasses should override bark. As it is, it doesn't take advantage of polymorphism.

    DOH! I meant to and forgot! Actually the subclass cocker was going to override "wag_tail" since they have short tails more or less wiggle their hind ends instead. ;-)
