On, no! Yet another "fun" language, i.e. a language that uses "fun" instead of the more standard "fn" or "func", just because it's 3-letters long and aligns better than 2- or 4-letter keywords (if you use 4-space indentation)! In fact, 2-letter indents are better - especially when your language suggests lines being less than 80-characters long!

The Linux kernel has a code style with 8 spaces and still has the 80 characters maximum. The coding style says "if you need more than 3 levels of indentation, you're screwed anyway, and should fix your program.". So not everybody agrees that you need deep indentation.

The kernel is in C. In OOP, there's at least one level coming from class declarations. 3 levels are more than normal in OOP!

That's true. And in the OOP case you usually have exception handling (i.e. try/catch blocks) as well, instead of "goto error" style error handling which is common in C.
