Nice, but why isn't the LLVM optimizer removing the move?
Is it lack of proper alias analysis?
Sounds like that is a separate issue worth pursuing.

Wouldn't #[inline(always)] on the aggregate constructor fix that? (it's not
great, but it's strictly better than a macro)
At any rate, shouldn't LLVM inlining heuristics catch that automatically as
well?
If not, that sounds like another separate issue.
