EDIT: to clarify, I'm not questioning the content. I'm just curious where the r+ was?

[tmandry]

Content looks fine, but I didn't approve it. Not sure how it got merged. cc @rust-lang/infra

[Mark-Simulacrum]

I've filed rust-lang/homu#56 and further discussion should happen there with regards to the bug.

[Mark-Simulacrum]

(Turns out there was not a bug here -- just commit included in an another PR).

[tmandry]

Ah ok, sorry for noise then.

In any case, thanks @gilescope for writing this :)
