I don't understand your example, `isSet` is always true and can never be false. Missed something?

It works because it's false when uninitialized (as default value). So if not initialized it represents Nothing value. When it is initialized it's Just T.

The only time `IsSet` would be false is when `NewOption` was not used to initialize the value.

e.g.

  var o Option[int32]
or could have `None` helper

  func None[T any]() Option[T] { return Option[T]{} }

  o := None[int32]()
