This article feels extremely imprecise. The syntax of the "language" changes from example to example, control structures like conditionals are expressed in English prose, some examples are solved by "do all the work for me" functions like the "toPdf()" example... This whole thing feels like an elaborate LLM fantasy. Is there any real, usable language behind these examples, or is the author just role-playing with ChatGPT?
