question: does refactor do multiple passes over the codebase until there's no diff?

[cktang88]

for example, in https://refactor.readthedocs.io/en/latest/tutorials/actions.html#replace I see 3 iterations. I'm mostly concerned about the impact this has on performance over large codebases.

@cktang88 that's true, it will run constantly until there is nothing to change.

This is something that we didn't actively consider in the past with the assumption that a full-run would only happen once a new rule is introduced and then runner frameworks like pre-commit would help them to limit. But we might start allowing a single iteration examples with the addition of chained actions (#57) which would essentially help you to scan and refactor a whole tree in one go.

If you have any performance critical examples, I'd love to hear more about them.
