Your PR no longer requires formatting changes. Thank you for your contribution!

Cool! Do you have any idea if this would make sense to implement at the VectorInterface level? Alternatively, to not necessarily mark everything as @is_primitive there but to already provide the implementation?

[kshyatt]

We could do it there if it's generic enough? I don't have a strong opinion tbh

[lkdvos]

It looks like all rules are implemented solely in terms of Mooncake or VectorInterface functions, so that might just work?

[kshyatt]

Nice, I can move these over tomorrow then

I think you still need the @is_primitive calls, since the VI rules are only defined for AbstractArray

Addressed by another PR over there 😉
