/// return this ExitCode from the `main` function, as demonstrated in the [type

/// # Differences from `process::exit()`
///
/// `process::exit()` accepts any `i32` value as the exit code for the process; however, there
/// are platforms that only use a subset of that value (see [`process::exit` platform-specific
/// behavior][exit#platform-specific-behavior]). `ExitCode` exists because of this; only
/// `ExitCode`s that are valid on all platforms can be created, so those problems don't exist
/// with this method.
