Was just about to post the link to my AST Ninja but I see somebody already beat me

As I just posted in José announces Livebook - a web application for writing interactive and collaborative code notebooks, I think that Livebook could be a great way to generate this sort of reference documentation (e.g., with executable examples).

I’ve seen a couple people already using Livebook to try stuff or document code from existing codebases, it seems to be great at that. I’m not sure it would be a good idea for public documentation like ex_doc(because of remote code execution), but for internal documentation it’s great.
If making it safe to use for public facing documentation is desired, I guess that Livebook having pluggable “interpreters” for the snippets could enable that. A “safe” interpreter could do some ast whitelisting, something like what Sand or tryelixir do.
