There's an article on kuro5hin titled Japanese for Nerds (I). Being the kind of guy that I am, I obviously had to take a gander there.
You gotta love geeky C-type function to Japanese translations like these:
1. Neg(Neg(Neg()), which is naku naku nai
2. Cond(Neg(Neg()), or naku nakereba
This reminds me of when I was first learning the language: I thought of it as just learning more syntactical structures--much like learning syntax for a programming language.
Commenting folks on kuro5hin are, as most commenters are nowadays, critical. Come on, folks, he's only put down one page to give a general idea of how he's presenting the language!
