@zygoloid s `repr_type` looks really promising. That should allow us to have a nice ABI and fix the bugs we currently have. @jiixyj could you try that version and check whether it actually fixes everything and gives us the nice ABI? (Note that you have to name the union to apply `[[no_unique_address]]`)
