A good book, I know and I love typography. My question was: why do you speak of typography about this wiki page "hello world" ? In this work shared here in Hacker News to get some feedback, I introduce a small language, lambdatalk, as a dialect of the lambda-calculus implemented as a Turing Machine, two old strange things nobody loves (and understands) but a few cute Phds. My opinion is that their basic concepts can be used to enlight the making of a language, what are functions, data structures, control structures. It's on the pedagogic side. On the practical side it appears that useful superstructures can be built on such solid infrastructures, via added built-in primitives and libraries. Maybe my paper is not clear enough for these ideas to be understood.
