In this pull request, I've fixed many mypy warnings too. That being said, it does not mean that we will use mypy for this project itself. We already use flake8 and pytype. These tools have been helping us to keep the quality at a high enough level. Spending more time for satisfying mypy is not the direction where we would like to head.

Looks good @seratch! Is there a way that we want to test that __all__ include the correct imports?

@mwbrooks

Is there a way that we want to test that all include the correct imports?

Good question! There is no way to write unit tests for it, but flake8 (linter) detects missing items if there is any.

[mwbrooks]

Cool, at least flake8 will help ensure we add them going forward!
