@AshesITR Resolved a merge conflict to prevent this one from drifting too much away from the main.

Hey @AshesITR I think it's time to start getting a release going in the next few weeks. Please drop this from the milestone if you're short on time (no pressure, just want to clarify what's still pending)

[AshesITR]

Sorry for the delayed reaction.
I'll see if I can invest some time today.
No worries if that's too late to the party for 3.0.2 😊

@MichaelChirico PTAL what you think. Still needs a NEWS entry, but the rest is complete.
I also took the freedom to split object_name_linters.R into separate files for the two linters to improve on the consistency R/*.R -> tests/testhat/test-*.R

[MichaelChirico]

Looks great, thanks!

[AshesITR]

This still needs a NEWS. Do you want to write a bullet?

[MichaelChirico]

whoops, got too excited :)

feel free to write one if you're still at it, I am logging off for the day
