[herodotus]

Reading "Lisp 1.5 Programmer's Manual" when I was a post-graduate student at Waterloo (around 1977) was a revelation to me. In particular, "Appendix B: The Lisp Interpreter" gives a version of the Lisp interpreter in just 39 lines of code! (The appendix includes notes, and is 3 pages long.) I remember using this code to figure out how Lisp evaluated recursive functions. Until this point in time I had programmed in Fortran, IBM 360 Assembler, Cobol and Pascal. They all required much more documentation, and, in many cases, experiments to figure out what would actually happen in certain cases.

I wish the idea of a definitive high-level semantic guide had become a thing. SwiftUI, for example, seems to be wonderful, but learning it, as far as I can tell, requires watching hours of talks, or working through many tutorials. What a contrast with McCarthey at. al's 1985 book.
