Thank you. This looks like a solid improvement, it just needs a rebase.

[llogiq]

@pitaj ping? Can you rebase?

[pitaj]

@llogiq sorry about the late response. Based on zulip discussion, I need to make a couple of changes:

• change lint group to pedantic
• add a check to avoid linting if other types from once_cell are used
