This is not a legal inference, and that's exactly the point Jeff made:

Just because it is written in C doesn't mean people will understand
it, it merely means that they will _think_ they understand it.

Nontheless, we have plenty of 
	/* You ARE supposed to understand this */
C-code already, so I don't see it as an objection to Jeff's patch.
