I actually like `anyhow` better than more involved crates, but we will need to have a good "error hygiene" if you will.

I actually wasn't aware of `anyhow` before writing this patch. And I have to say that I really like `anyhow` because it is simpler than other crates in this space while offering much of the same functionality.

I think it is inevitable that we'll want to use a crate like `anyhow` for more advanced error handling. If nothing else, it can help cut down on boilerplate code around error handling.
