* `anyhow::Result<V>` is a type alias for `Result<V, anyhow::Error>`.
* `anyhow::Error` is generic and it can hold any `Error` implementation without changing the type signature.
* `anyhow::Error` is essentially a wrapper around `Box<dyn Error>`. As such it's again generally not
a good choice for the public API of a library, but is widely used in applications.
* 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
of `(T, error)` from Go.
