This example demonstrates techniques for performing custom error handling
in a derive-input receiver.
1. Using `darling::Result` as a carrier to preserve the error for later display
1. Using `Result<T, syn::Meta>` to attempt a recovery in imperative code
1. Using the `map` darling meta-item to post-process a field before returning
1. Using the `and_then` darling meta-item to post-process the receiver before returning |

This example demonstrates:
- The behavior of a derived `FromMeta` implementation for heterogeneous enums
(i.e. enums that include a mix of unit, newtype and struct variants).
- Using `#[darling(word)]` to specify a unit variant to use when a receiver field
is specified without a value (i.e. a unit variant to use for deriving the
`FromMeta::from_word` method).
- Using `#[darling(default)]` on a receiver field to fall back to `Default::default()`
for the enum's value when the receiver field is not specified by the caller. |
