I don't know where this meme started . . .
Possibly on page 321 of the blue Camel, just under the "Class Inheritance" subheading:
As with the rest of Perl's object system, inheritance of one class by another requires no special syntax to be added to the language.
The -> operator denotes a referance, which has plenty of use outside OO. In this case, were referancing a subroutine from a bless'd variable. I'm not sure about SUPER::.
Reinvent a rounder wheel.
