// Swift's untyped errors are a goddam PiTA. Here's the pattern I use to try to work around this.
// The goal is basically to try to guarantee that every throwing function in the app throws an
// ApplicationError instead of some unknown error type. We can't actually enforce this statically
// But by following this convention we can simplify error handling

enum ApplicationError: Error, CustomStringConvertible {
    
  // These are application-specific errors that may need special treatment
  case specificError1
  case specificError2(SomeType)
