Andrew Kelley said they'll only start writing the actual documentation once they hit 1.0 so they don't need to update it all the time. I personally find parts of the language unintuitive enough that I'll just wait.

I don't get the problem with `fn`, though. Pretty much every language uses abbreviations like that and I've never heard anyone complain about it: enum, char, int, uint, def, ...you get used to it quickly, you need to build a mental model for them either way.
