--- Comment #9 from Peter Harris <peter.harris at hummingbird.com> ---
In general, I am opposed to language-specific cruft in the protocol
description.

If I may make a suggestion, all structs/requests/replies/etc should be treated
as packed. Instead of adding a "packed" attribute, explicit padding should be
added to the few remaining objects that currently contain implicit padding.

c_client.py (and/or xtypes.py) could then be enhanced to automatically notice
structs that don't fit the default C alignment rules and add whichever
annotations the C compiler needs.

What do you think?
