Using `Optional[str]` instead of just `str` will let the editor help you detect errors where you could be assuming that a value is always a `str`, when it could actually be `None` too.

`Optional[Something]` is actually a shortcut for `Union[Something, None]`, they are equivalent.

This also means that in Python 3.10, you can use `Something | None`:

//// tab | Python 3.10+

```Python hl_lines="1"

        // Acquire the shared lock allowing interruption.
        acquireSharedInterruptibly(-1);
        return getValue();
      }

      /**
       * Implementation of the actual value retrieval. Will return the value on success, an
       * exception on failure, a cancellation on cancellation, or an illegal state if the
       * synchronizer is in an invalid state.
