The subject of power came up and the two of them wondered how large a language one would have to make to get great power. With as much panache as I could muster, I asserted that you could define the “most powerful language in the world” in “a page of code.” They said, “Put up or shut up.”

First, I wanted the program to be more like McCarthy’s second non-recursive interpreter--the one implemented as a loop that tried to resemble the original 709 implementation of Steve Russell as much as possible. It was more “real.” Second, the intertwining of the “parsing” with message receipt--the evaluation of parameters which was handled separately in LISP--required that my object-oriented interpreter re-enter itself “sooner” (in fact, much sooner) than LISP required. And, finally, I was still not clear how send and receive should work with each other.

I think JavaScript was designed in a week as well

The major differences from the official Smalltalk-72 of a little bit
later were that in the first version symbols were byte-coded and the
receiving of return of return-values from a send was symmetric—-i.e.
receipt could be like parameter binding—-this was particular useful
for the return of multiple values. For various reasons, this was
abandoned in favor of a more expression-oriented functional return
style.

This had been an interesting holiday from our official “iconic programming” pursuits, and I thought that would be the end of it. Much to my surprise, only a few days later, Dan Ingalls showed me the scheme working on the NOVA. He had coded it up (in BASIC!), added a lot of details, such as a token scanner, a list maker, etc., and there it was-–running. As he liked to say: “You just do it and it’s done.”

Dan loved to bootstrap on a system that “always ran,” and over the next ten years he made at least 80 major releases of various flavors of Smalltalk.
