Guy Steele & Richard Gabriel: 50 in 50

For those who like their PL History presented in avante guard beat poetry, a video of Steele & Gabriel's 50 in 50 speech at JAOO is made to order. Or as the link says:

A fun, artistic and enlightning presentation full of interesting facts - and who better to do it than Richard P. Gabriel and Guy L. Steele (the great Quux). Nothing more to say than the rallying cry; More cowbell!

Passing aside the Stephen Wright comic delivery of the two speakers, there are a lot of interesting thoughts, though very few are dwelled on. I think the most interesting things were the languages that they chose as expositions for the major ideas that they covered. Here's the ones that I picked out (though I ended up with only 49):

yet another oop formalization: class as abstract automata

ABSTRACT

The Formalization of the OOP Paradigm: INHERITANCE OF ABSTRACT AUTOMATA
is devoted to discussion of the inheritance
relation on sets of Mealy automata. It continues study

Formalization of the OOP Paradigm

in which:

- the concept of abstract data type (or, what is the same, of a class)
is treated as an abstract automaton;

- relations of inheritance and polymorphism are introduced on sets of the Moore automata.

Proposed formalization of OOP notions significally differs from the
formalization of Luca Cardelli (see, for example, "A Semantics of Multiple Inheritance",
1988, Information and Computation 76, 138-164, 1988; http://lucacardelli.name/; ).
