To be consistent with the other adjoints, the copy!(A, Ac) would happen before calling the pullback, and then you can just pass A in the f_pullback! call. I am not opposed to the current order/approach but do value consistency as it helps in reading the code at a later stage.

I think I would like to do a follow up PR where I refactor a bunch of this into the same order and format, but didn't want to pollute this PR too much with simple formatting changes.

Same comment about order of operations.

[lkdvos]

I think I addressed most of the remarks here, except for the order of operations. Would you be okay with me leaving that for a follow-up PR? I would like to refactor some of this code a bit more, and I don't want to pollute this PR with a bunch of formatting changes if possible.
