Understood. I've been trying to help the drm folks walk a line between
having a bunch of custom macros hidden away in the drm includes and
building up generalized versions that are actually helpful beyond drm.
But I can see that it doesn't help to have a "do two things at the same
time" macro for the assignment checking.
