> My view is that sample code such as this should be as idiomatic as possible and that means providing a sample demonstrating a typical real use case. So seeing "unwrap" in this context doesn't sit well with me.

I've starting trying to use `if let Some/Ok(...) = ...` in examples for my projects rather than `unwrap` for pretty much this reason. I feel like it strikes a pretty good balance between providing a relatively terse example without the risk of implying that `unwrap/expect` is considered normal usage for the library.
