    my Dog $spot;
    my $pub = $spot->procreate;

Sure looks like a factory method to me.  Just because you don't get to say
my Dog $pup for some optimization doesn't mean they're impossible.

    package Mammal;

    sub hair_color { ... }


    package Dog;
    use base qw(Mammal);

    sub CREATE { bless({}, "Dog") }


    package main;

    my Dog $spot;
    $spot->hair_color("blue");  # works just fine

I'm not proposing revamping the entire OO system, and I'd like to know what
made you think I was.
