Sorry Ben, but (assuming "device" is in a register and you've got a
register offset addressing mode---both of which are perhaps dangerous
assumptions) device->foo.bar.baz is about as fast as you can get:

	decl	24(r9)	# device->foo.bar.baz--; /* sample vax code */

("with" in Pascal generally puts a pointer to the object into a
register; "device" is already a pointer to the object.)
