Literate Coffeescript comes out of the box with Coffeescript. I kind of like it, especially for complicated algorithms where the ammount of comments exceed the lines of code. Here's an example [1] of a kd-tree implementation in literate coffee. It reads beautifully on Github as well, since it's Markdown!

Literate coffescript falls under one one of the pseudo literate tools, i.e. just nice comments. Not to discredit that approach, its just a compromise for most of the benefit. Many of those tools avoid the extra step of having to expand macros and such, before compilation/being interpreted. I ended up borrowing the watch feature, which aids the workflow

I have found that writing code in arbitrary order is a key feature that is missing in comment-flipping. Not worrying about the order of compilation is defended by saying we can just use functions to do that, but I often find the little stuff such as error tests, etc., are best moved out of the way and replacing them with function calls is problematic if your checking on sane input.
