The expect lint is really great, been looking forward to that for a while.

Still waiting for more flexible const generics 🤞
fs::exists() was a nice little improvement that I didn't know about until I read this announcement.
- It's a subtle difference between that and path::exists().
  
  path::exists() == false might just mean you can't use it (if path::exists() cannot access a file due to e.g. permissions, it'll return false)
  
  fs::exists() == Ok(false) means it's definitely not there (permissions error will cause an Err to be returned)
