@waketzheng no need to change about this PR but it would be great to have two separate PRs in the future when you want to refactor the code. In this example it would be:

• PR for fixing enums not quoted
• Adding type hints

Having everything as a single PR makes it really hard to review actual logic changes. Thanks!
