Should we have an `InspectLeft` and `InspectNone`?

[bash]

We have a SelectLeft for Either. It might be nice to also have inspect for the error case. Use case: Reading an optional value while logging a warning if it's not present:

ReadConfigurationFile()
  .OrElse(() =>
  {
      logger.Warning("Configuration file is missing"));
      return Option<ServerIniConfiguration>.None;
  });
