Review comment:
Is `abort!` the standard way to blow up a macro?

Review comment:
This is like if you mark something with a `no_derive` attribute you
don't derive `Debug`? Naming is a bit wonky here

Review comment:
Instead of consuming `self` with `into_iter` could you have a method
that returns an `Iterator` over references so you don't have to clone, since
`write!` I assume doesn't need owned values? But this may not matter if
`clone`ing these `Array`s isn't expected to be expensive.
