fn main() -> anyhow::Result<()> {
    let expected_some = None;
    auto_context!(expected_some)
}
```

```sh
$ cargo run --example option
Error: expected_some in option::main at examples/option.rs:6:5
```

### With `Result`

```rust,no_run
use anyhow::Result;
use anyhow_auto_context::auto_context;

fn main() -> Result<()> {
    auto_context!(foo())
}

fn foo() -> Result<()> {
    auto_context!(bar())
}

fn bar() -> Result<()> {
    anyhow::bail!("my error")
}
```

```sh
$ cargo run --example result
Error: foo() in result::main at examples/result.rs:6:5

Caused by:
