Scheme was invented as a consequence of Sussman & Steele’s discovery that lexical closures in the lambda calculus had essentially an identical implementation to a fully elaborated version of Hewitt’s actor model.

I do wonder what a language with the same “taste” and minimalism as Scheme but embracing the actor model would look like. Erlang?

Even better if someone could figure out how to harmonize them in the same language: “There are exactly two ways to do it, and they’re interchangeable.”
