THe HN title seems very misleading to me. How is this, in any sense of the word, "formal?" I don't see that particular word used to describe this tool on the web page itself.

The site does describe it as a "programming language," which feels like a novel use of the term to me. The borders around a term like "programming language" are inherently fuzzy, but something like "code generation tool" better describes CodeSpeak IMHO.
