These are some notes on languages. The design of Keykos draws much from language design. E is a language built from ground up with these ideas in mind.

Some old good stuff

Mark miller has found some stuff that should have influenced Keykos but didn’t.

Morris’s 1973 Protection in Programming Languages has just the perspective that we push here. I think that eval is needed to bind identifiers in program text to a set of values. Then Morris could have built the factory. Morris refers to the language 1968 PAL from which Charlie Landau would bring ideas. (Charlie contributed to the Keykos architecture.)

See too this which has more such ideas.
