To be honest, I'm not really wild about this one. All the array users
I know of (key/button, xdg surface states) are uint32_t. I'd prefer to
add a pretty-printing hint to the protocol - this could specify how to
interpret arrays, and also scratch my long-standing itch of printing
uints with %x rather than %u when it makes sense to ...

Cheers,
