If you check the previous app, in the UI you can see that, up to now, it lets the client decide the `id` of the `Hero` to create. 😱

We shouldn't let that happen, they could overwrite an `id` we already have assigned in the DB. Deciding the `id` should be done by the **backend** or the **database**, **not by the client**.

```Python
    first_name="john", last_name="doe"
```

It's a different thing.

We are using colons (`:`), not equals (`=`).

And adding type hints normally doesn't change what happens from what would happen without them.

But now, imagine you are again in the middle of creating that function, but with type hints.

At the same point, you try to trigger the autocomplete with `Ctrl+Space` and you see:

                sb.append("The option -").append(option.getOpt());
                if (option.getLongOpt() != null) {
                    sb.append(",--").append(option.getLongOpt());
                }
                sb.append(" is deprecated ");
                if (option.getDeprecated().isForRemoval()) {
                    sb.append("and will be removed in a future version");
                }

	// if mode and retain until date are not set.
	// Can happen when bucket has default lock config set
	if action == policy.PutObjectRetentionAction &&
		r.Header.Get(xhttp.AmzObjectLockMode) == "" &&
		r.Header.Get(xhttp.AmzObjectLockRetainUntilDate) == "" {
		return ErrNone
	}

  public void testPartiallyConstructedManager_transitionAfterAddListenerBeforeStateIsReady() {
    // The implementation of this test is pretty sensitive to the implementation :( but we want to
