> Does anyone know of a language like this? My first thought was that it would probably be something Lisp-y, but I realized I’m not sure if I’ve ever seen a language that was scaled to individual coders by design.

The Lisp Machines were designed to be individual workstations, in an era when virtually all computers were batch or time-shared machines. I remember seeing a video from Symbolics, the leading Lisp Machine vendor, from the late 80s. Some VP of product development was on the screen, and he was talking the usual business stuff: blah blah improve developer productivity, blah blah features, blah blah. Then he said something interesting, something I've never heard from a hardware or software executive: "We want to make it possible for a small team of developers to build large projects, and for a single person to build a smaller project." So the idea of an individual programmer or a small strike team being able to build software of virtually any size is very much part of the Lisp culture.
