Passing these by value won't be ok of course, but that's fine.
I plan to combine this with https://github.com/eqrion/cbindgen/pull/333 to
actually be able to share representation for ~all the things, this is just the
first bit.
Box<T>, Atom and Arc<T> will be much easier since cbindgen can understand them
without issues.
It's boxed slices the only ones I should need something like this. I could avoid
it if I rely on Rust's internal representation, which we can per [1], but then I
need to teach cbindgen all about slices, which is generally hard, I think.
