That is not the same as declaring default values like would be with:

```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.

    assertThat(parse("http://[::1]/").host).isEqualTo("::1")

    // ... but they're included in toString().
    assertThat(parse("http://[::1]/").toString()).isEqualTo("http://[::1]/")

    // IPv6 colons don't interfere with port numbers or passwords.
    assertThat(parse("http://[::1]:8080/").port).isEqualTo(8080)
    assertThat(parse("http://user:password@[::1]/").password).isEqualTo("password")

	if sqldb, ok := connPool.(*sql.DB); ok && sqldb != nil {
		return sqldb, nil
	}

	return nil, ErrInvalidDB
}

func (db *DB) getInstance() *DB {
	if db.clone > 0 {
		tx := &DB{Config: db.Config, Error: db.Error}

		if db.clone == 1 {
			// clone with new statement
			tx.Statement = &Statement{
				DB:        tx,
				ConnPool:  db.Statement.ConnPool,
				Context:   db.Statement.Context,
