* `anyhow::Result<T>` is generic and it can hold any `Error` implementation without changing the type signature.
* Actual error type inside of it can be extracted for examination if necessary.
* Functionality provided by `anyhow::Result<T>` may be familiar to Go developers, as it provides similar usage patterns and ergonomics
